Opening ceremony on March 21 2018 in Shanghai of the joint laboratory of our partners Shanghai Jiao Tong University Medical Imaging Team with Prof Sanven Tu and Pulse medical imaging!! Congratulations!!
The team of Prof Gianluca Campo, Ferrara university in Italy, has carried out a very interesting study including 3 steps: 1) QFR reproducibility in non-culprit (NCL) coronary lesions; 2) diagnostic accuracy of QFR; and 3) long-term clinical outcomes of NCL stratified based on QFR. The reproducibility and accuracy were all excellent and consistent with other studies, and in this small cohort they concluded that QFR may be a reliable tool to guide coronary revascularization of NCL’s in ST-segment elevation MI patients.
The team of Prof Serruys has studied the impact of coronary remodeling and lumen dimensions as measured by Medis QAngioCT on fractional flow reserve FFRCT by Heartflow. They conclude that in patients with nonobstructive coronary artery disease, expansive remodeling has on impact on the CT-based FFR.
This work was carried out by the team of Prof Akasaka at Wakayama Medical University in Japan.
They analyzed fixed-flow QFR (fQFR) and contrast-flow QFR (cQFR) in 75 prior-MI-related coronary arteries and 75 non-prior-MI-related coronary arteries. The diagnostic accuracy of fQFR <_ 0.8 and cQFR<_0.8 for predicting FFR<_0.80 was found to be numerically lower in the prior-MI-related coronary arteries compared with the non-prior-MI-related coronary arteries (fQFR: 77% vs 87%; and cQFR: 87% vs 92%).
We are happy to announce that as of today QIvus® Research Edition 3.1 is available. The most important new features are:

Wouter M van Everdingen and his colleagues from UMCUtrecht in the Netherlands have compared strain analyses parameters in an attempt to predict which patients would benefit from Cardiac Resynchronization Therapy (CRT). They compared CMR feature tracking with Medis'QStrain, MR tagging and Echo speckle tracking in 27 CRT candidates. The conclusion of this work was that CVMR feature tracking is a potential clinical alternative for the MR tagging approach and echo speckle tracking, especially in the detection of discoordination in CRT candidates.
Researchers at NIH aimed to assess the clinical value of global and regional strain using FT-CMR in patients with ARVD/C and compared four different software packages. Despite large intersoftware variability of FT-CMR derived strain values, they found that all four packages were able to distinguish overt ARVD/C from control subjects by both global and subtricuspid strain values. The only package able to distinguish preclinical from control subjects specifically in the subtricuspid region, was QStrain. This suggests the potential to identify early ARVD/C prior to overt disease expression. Overall, the Medis QStrain solution was the most sensitive and reproducible among the four tested solutions.
This review summarizes the current state-of-the-art of invasive diagnostic methods during heart catheterization and highlights the potential role that an integration of anatomical and functional information enables.
The team of Lourens Robbers from VUMC in Amsterdam have concluded from their study that the presence of microvascular injury profoundly affects MOLLI-measured native T1 values. T2* mapping suggested that this may be the result of intramyocardial haemorrhage.
The team has carried out an in vitro validation of complex lesions in plexiglass phantoms using the QAngio CT analytical tool . They concluded that CTA is accurate for the evaluation of bifurcation lesions.
224 coronary segments were analyzed in 85 patients. Overall accuracy of contrast QFR (cQFR: no wire, no adenosine) to detect ischemia on SPECT MPI was 90%. They concluded that a good relationship between cQFR and SPECT MPI was found. QFR independently associated with ischemia on SPECT MPI and shows incremental value to detect ischemia compared to clinical and QCA parameters.
When should we use contrast material in cardiac MRI?
They analyzed 151 coronary arteries with intermediate stenosis in 142 patients. QFR had good correlation (r=0.80, P<0.0001) and agreement (mean difference: 0.01±0.05) with FFR. After applying the FFR cut-off ≤0.8, the overall accuracy rate of QFR ≤0.8 was 88.0%. On receiver operating characteristics analysis, the area under the curve was 0.93 for QFR. They concluded that QFR had good correlation and agreement with FFR and high diagnostic performance in the evaluation of intermediate coronary stenosis, suggesting that QFR may be an alternative tool for estimating myocardial ischemia.
The team of Dr Matthew Budoff concluded in a paper using Medis’ QAngio CT tool that treatment with testosterone gel for one year compared with placebo in older men with sympotomatic hypogonadism was associated with a significantly greater increase in coronary artery noncalcified plaque volume as measured by coronary computed tomographic angiography.
On Wednesday December 14, 2016 Medis received the Deshima 2016 SME Business Award for its contributions to innovations and collaborations in the field of medical imaging over a period of 15+ years at a ceremony in Tokyo. Vice-minister Maarten Camps handed over the Delft Blue Plaque.
Tu et al have published the results of the FAVOR II Pilot study and concluded as follows:
The favorable results of the contrast-flow QFR that does not require pharmacologic hyperemia induction bears the potential of a wider adoption of FFR-based lesion assessment through a reduction in procedure time, risks and costs.
From the paper: “ After six months, compared to the placebo group, those in the fish oil group had less fibrosis, or thickening and scarring, of the heart muscle in the region of the heart attack. The also had less blood left in the left ventricle of the heart after the heart muscle fully contracted, which means the heart was pumping more effectively.”
They used the T1-module of QMass and concluded that caffeine intake inverts the adenosine effect during stress perfusion CMR as measured by T1 mapping. Therefore, the ∆T1 (rest T1 minus T1 stress) can be used as a benchmark for the validity of the stress induction by adenosine at cardiac MR perfusion studies
Dr. Symons and team members compared plaque measurement reproducibility (scan-rescan) on 2 state-of-the-art CT scanners. Group (1) of 20 patients had rescan within 30 days on same scanner, while group 2 had rescan on different scanner. Plaque volumes were analyze with Medis’ QAngio CT Research Edition software. Conclusions: State-of-the-art CCTA shows excellent total, calcified and non-calcified coronary plaque reproducibility, especially with the same CT scanner. CCTA is a valid tool to reliably assess change in coronary plaque volume in both research and clinical routine.
The team from Mount Sinai Hospital, New York with last author AS Kini, MD demonstrated in a multimodality intravascular imaging study with QIvus that among a total of 383 patients ( 268 men and 115 women) with stable CAD referred for coronary angiography, that there was no difference in plaque characteristics as assessed by registered IVUS, OCT and NIRS data sets.
The new QFR for the functional assessment of coronary narrowings from 3D QCA attracted lots of attention. There were live cases from Massy (FR), Essen (DE) and Beijing (China), scientific presentations on the results of clinical trials, hands-on workshops organized by GE in their educational center, and interviews. In the following you will find pictures and the appropriate links.Early Data Hint at Good Results With Angiography-Derived FFR
Medis successfully presented the latest Medis Suite cardiac MR software at the Face-off session, EuroCMR held in Florence, Italy. The other participants in the face-off session were Circle CMR42 and Pie Medical. The task for all three participants, was to analyze 1 challenging case, and have a side-by-side comparison of the results. Medis performed very well at this face-off session by carrying out the case analysis in a truly live fashion and from scratch, by emphasizing the new automated segmentation and editing tools. We finished our presentation well within the allotted 15 minutes time slot, and even managed to show additional RV functional analysis results. The organizers commented that our results were good and accurate.
The team of Yeon Hyeon Choe, Samsung Medical Center, Seoul, S-Korea have carried out a study to determine criteria for the diagnosis of LVNC.
They measured the left ventricular trabeculated volume and the total LV myocardial volume and concluded that a trabeculated LV myocardial volume above 35% of the total myocardial volume is diagnostic for LVNC with high specificity.

Shengxian Tu and his team have carried out an interesting study, whereby they compared two geometrical models of the same vessels, one by CTA and the other by 3D QCA. Image based FFR was computed using CFD simulations, applying the same hyperemic flow rate derived from the angio images at the inlet boundaries. They found a moderate agreement between FFRCTA and FFRQCA, and based on these observations suggest that image resolution has a significant impact on FFR computation.For further reading, refer to the article on http://link.springer.com/article/10.1007/s10554-015-0797-5?no-access=true.

A growing phenomenon in the world of medical image processing is that of “Grand challenges”. The great advantage of such challenges is that all algorithms are evaluated on the same data and using the same evaluation procedure.
This year at the MICCAI conference the Biomedical Imaging Group Rotterdam of the Erasmus MC organized a challenge on the automatic detection and quantification of stenoses in coronary CTA data (http://coronary.bigr.nl/stenoses/).The challenge contained 48 multi-center multi-vendor CTA datasets. In total 11 teams from different institutes participated in the challenge. Teams had to (semi) automatically detect and quantify coronary lesions in the CTA datasets and submit their results to an online evaluation framework. Teams where ranked according to a number of criteria in three categories: detection (ability to detect significant stenoses), quantification (comparison with observer and QCA stenoses grades) and finally lumen segmentation (compared to observer drawn contours).
At the Division of Image Processing (LKEB), Department of Radiology at the Leiden University Medical Center (LUMC), the CTA group have developed and validated robust algorithms for extraction and segmentation of coronary CTA data. This work has largely been done in within the STW CADAStr project in close collaboration with the LUMC department of cardiology and Medis medical imaging systems. These algorithms have already contributed to a number of international high ranking publications both from inside and outside the LUMC.
On the 1st of October, at the start of MICCAI 2012 conference in Nice, France a team from the LKEB/Medis (Alexander Broersen and Pieter Kitslaar), ranked 1st place in the detection and 2nd place in the quantification and segmentation categories. Based on these ranks, they were the overall winners of the on-site challenge. Congratulations, job very well done!! The algorithms are now part of the QAngio CT RE analytical software product; commercialized by Medis Specials bv (www.medisspecials.com) a Medis BV company.
Medis released on March 29, 2012 the new QAngio XA V7.3 quantification software. It has a complete new look with new icons and a tabular wizard for intuitive and fast navigation through the analysis workflow. Other very important items include:

Medis released on Sept 1, 2011 version 2.1 of its quantitative analysis software solution QIvus for intravascular ultrasound. This new version of the software has extended possibilities to review and analyze IVUS studies with tissue characterization data that visualize plaque and to also review and analyze optical coherence tomography (OCT) studies.
"We are continuously listening to our highly valued customers, and take their comments and wishes very seriously, so that we can come up regularly with new versions based on the wishes from the field. Both the clinical users, the researchers and the core lab users are very important to us. This version of QIvus 2.1 enables medical professionals to quickly analyze data acquired with all currently available intravascular imaging systems, meaning that we can process vendor-independent data sets," said Daniel Garcia, VP M&S of Medis medical imaging systems. "We are well-known for our segmentation quality and that translates into tools by which the users can analyze image runs with a minimum of effort and to get more out of the data that is already available to them."
One of the major strong points of QIvus is the extremely efficient editing capabilities of the otherwise automatically detected contours, which drastically reduces the time needed to obtain validated results from the large number of grayscale or OCT images. Analyzing IVUS or OCT image data sets becomes a matter of minutes.
This means that important data, such as plaque burden results in IVUS images can be obtained quickly and easily. In a similar way, the software provides detection of stent struts in OCT images, allowing assessment of stent malapposition and neo-intima formation.
Important new features include the IVUS-analysis of multiple stents in the same segment, the Z-offset correction in OCT image runs, and export of all analysis results to Excel, including OCT stent strut analysis and subsegment analysis, as well as improved support for Japanese and other multi-byte languages. Here again, the workflow for editing the OCT stent strut analysis has greatly improved.
For those who have data sets with tissue characterization available, QIvus 2.1 also offers the option to view and analyze the areas marked as plaque and calculate the distribution of the various plaque components. The software supports both Boston Scientific iMap™ and Volcano® VH® IVUS data sets. The iMap and VH data can be reviewed alongside the grayscale image data, and analyzed just as quickly.
All in all, the new QIvus 2.1 offers fast, accurate and reliable quantitative analysis for more types of intravascular image data sets, and builds upon the established reputation of the QIvus product.
Medis today released version 2.0 of its quantitative analysis software solution QIvus for intravascular ultrasound. The new version of the software makes it possible to review and analyze IVUS studies with tissue characterization data that visualize plaque and to also review and analyze optical coherence tomography (OCT) studies.
"This version of QIvus 2.0 enables medical professionals to quickly analyze data acquired with different intravascular imaging modalities," said Hans Reiber, President and CEO of Medis medical imaging systems. "The software gives them the tools to analyze image runs with a minimum of effort and to get more out of the data that is already available to them."
QIvus minimizes the need to edit automatically detected contours, which drastically reduces the time needed to obtain validated results from the large number of grayscale or OCT images. Analyzing IVUS or OCT image data sets becomes a matter of minutes.
This means that important data, such as plaque burden results in IVUS images can be obtained quickly and easily. In a similar way, the software provides detection of stent struts in OCT images, allowing assessment of stent malapposition and neo-intima formation.

The software supports both Boston Scientific iMap™ and Volcano® VH® data sets. The iMap and VH data can be reviewed alongside the grayscale image data, and analyzed just as quickly.
All in all, the new QIvus 2.0 offers fast, accurate and reliable quantitative analysis for more types of intravascular image data sets.
Today, Medis released a new version of QFlow, its application for the quantification of flow and velocities in phase-contrast MR studies.
In this new version users will find, among other features, even faster contour detection and many improvements in the interface.
QFlow already featured fast, three-click contour detection for regions of interest. In QFlow 5.2, contours for up to four regions of interest can now be detected at once.
Cardiac quantification software supplier Medis today released a new version of its QMass MR software. QMass MR 7.2 makes the analysis workflow faster and offers automatic scar tissue segmentation.
QMass MR is the Medis software solution for the quantitative analysis of cardiac MR. It enables clinicians, researchers and technicians to analyze global and regional cardiac function, scar tissue and viability, and cardiac function at various stress levels.
The new version features many shortcuts and interface improvements that make working with the software faster and more intuitive. Examples are scrolling through series in the Movie Tool and one-click selection of the ED or ES phase in the Study Matrix.
For clinicians or researchers performing cardiac MR scar tissue analysis, QMass MR 7.2 provides two major improvements.
First of all, scar tissue analysis has become significantly faster because of the introduction of automatic segmentation. While the analysis can still be monitored and modified at each of the four analysis steps, the automatic segmentation reduces manual editing to a minimum.
Secondly, the scar tissue analysis in QMass MR now features double thresholding. This makes it possible to differentiate the infarct core from the peri-infarct region, and quantify those regions.
Medis medical imaging systems and MeVis Medical Solutions AG [ISIN: DE000A0LBFE4], a leading medical imaging software company with focus on dedicated, disease-oriented clinical applications, today announced a strategic alliance, which may lead up to a potential take-over of Medis by the MeVis Group.

Today, Medis releases the new version of its quantitative analysis software for peripheral and coronary vessels in X-ray angiograms, QAngio XA 7.2.
This version features two major innovations in the analysis of bifurcated arteries: dedicated analysis models and edge segment analysis.
QAngio XA 7.2 gives clinicians and researchers two dedicated analysis models for bifurcations. The T-shape and Y-shape analysis models make it possible to handle differences in vessel morphology, device, and intervention strategy.
QAngio XA 7.2 also optionally features analysis results for all stent and ostial edge segments in bifurcated vessels. This allows clinicians and researchers to focus on specific segments of the vessel wall, such as stent edges, ostia of distal branches and the bifurcation core.
The QAngio XA 7.2 innovations make bifurcation analysis more flexible and enable more targeted follow-up of patients after intervention.
Started as an innovation in the Medis training program earlier this year, the e-learning sessions have proven to be a valuable educational tool. E-learning is here to stay and registration for the new season has started.
E-learning sessions consist of a 30 minute training, followed by a 10-15 minute question round. The training only requires an internet connection and a standard web browser. No additional software needs to be installed.
Currently, sessions provide a functionality overview of one of the Medis applications QAngio XA, QMass MR or QPlaque MR. Sessions focusing on new releases and specialized sessions will be scheduled in the future.

This year's edition of the self-assessment test, which is developed in joint collaboration by Medis and SCMR, will also be available to visitors of EuroCMR 2008, after its featuring at SCMR 2008 in Los Angeles last February.
The test enables cardiologists to assess their skills in reading cardiac MR studies. It consists of eight sets of questions, contributed by peers from the field who have selected their most interesting cases. Participants are shown their score for each set of questions that they complete.
Registration is not required for the Medis SCMR self-assessment test: it will be available to the public on a workstation next to the Medis presentation outside the EuroCMR conference hall. EuroCMR 2008 will be held in Lisbon, Portugal, from May 22 through May 24.
Medis' research partner in vessel wall imaging, the Division of Image Processing (LKEB) at the Leiden University Medical Center's Radiology Department, has been awarded the ECR 2008 first prize for Best Scientific Paper in the category "Computer Applications".
The paper, titled "Automatic detection of atherosclerotic carotid plaque from combined magnetic resonance angiography and vessel wall images", was presented by Ronald van 't Klooster, MSc. It was chosen by the ECR committee for Scientific Papers because of its scientific content, the quality of the images, and the quality of the presentation.
Today, Medis released version 1.1 of its software solution for the analysis of stenoses in CTA studies, QAngio CT.
The new version features improvements based on customer feedback. Enhancements include improved segmentation and detection, improved performance, more versatile viewing, and additional reporting.
The 2008 edition of the European Congress of Radiology's IMAGINE exhibit will feature a presentation of current research projects at Medis and its research partner LKEB (Division of Image Processing, Leiden University Medical Center).
The ECR high-tech specialty exhibit highlights the latest technological developments from ten European research institutes, university groups and research departments of industrial companies. It gives radiologists the opportunity to see and discuss the potential of new techniques.
Medis and LKEB will present ongoing research in two areas of interest: the quantification of brain MRI and the quantification of the vessel wall in multi-spectral MR studies of carotid arteries.
The US Food and Drug Administration (FDA) has provided market clearance for QPlaque MR, Medis' software solution for the analysis of the vessel wall in multi-spectral MR studies of the carotid arteries.
This clearance of Medis' latest solution for vascular analysis means that clinicians and researchers can now obtain reliable quantitative data to support the assessment of vessel wall condition in patients with atherosclerosis.
Come see us at one of the following congresses and discover how Medis software products can help you make post-processing more accessible and more efficient.
