QFR shows high correlation, diagnostic accuracy and discriminant function with FFR

In the field of coronary revascularization, where identifying reversible myocardial ischemia is paramount, FFR and iFR are standard but underutilized due to various limitations. QFR, an angiography-derived method, emerges as a potential game-changer, providing functional assessment without additional wires or hyperemic agents and showcasing a shorter measurement time than invasive methods. In conclusion, the study, aligning with ongoing trials, suggests that a QFR-guided strategy could simplify, enhance safety, and cost-effectively guide revascularization decisions. Furthermore, the findings position QFR as a promising tool to boost the adoption of physiology-based revascularization in routine clinical practice.

The use of two angiographic projections within Medis QFR® and the benefits over single-view projections.

The Medis QFR® approach is based on the 3D reconstruction of a selected coronary segment from two X-ray angiographic views at least 25 degrees apart, and on the assessment of the flow velocity through the vessel following strict acquisition guidelines.

From research to release: additional normal values included in the release of Medis Suite MR

Last year a paper was published on normal values scanned on a 3T MR machine (doi: 10.1002/jmri.28903). In this study MRI reference ranges of left and right ventricular (LV and RV) morphology and function were established, based on a large multicenter cohort.
