vFFR :: Pie medical imaging
The vFFR workflow builds a 3D reconstruction of coronary artery and assesses pressure drop, resulting in a vFFR value. Furthermore, with the 3D reconstruction anatomical lesion information is provided, like the percentage stenosis. Functional lesion …
健心知著 | QFR vs FFR指导冠状动脉血运重建（FAVOR III欧洲）： …
2024年11月22日 · 指南建议采用血流储备分数（FFR）来评估冠状动脉中度狭窄的功能性，但这需要在有创冠状动脉造影时放置压力导丝。 定量血流比（QFR）是一种基于血管造影估算FFR的计算方法，不需要使用压力导丝。 相比于FFR，采用QFR是否有非劣效的临床结局尚不明确。 本研究（欧洲 FAVOR III）是一项多中心、随机、开放标签、非劣效试验，旨在研究与FFR相比，基于QFR的诊断策略是否能产生非劣效的临床结局。 本文于2024年10月发表于Lancet杂志。 该试 …
Angiography-Based Fractional Flow Reserve: State of the Art
Quantitative flow ratio (QFR) developed by Medis Medical Imaging System, Leiden, the Netherlands, and Pulse Medical Imaging Technology, Shanghai, China, is obtained from two diagnostic angiographic projections, at least 25° apart to generate a 3D QCA model.
Diagnostic accuracy of quantitative flow ratio (QFR) and vessel ...
Angiography derived FFR reveals good performance in assessing intermediate coronary stenosis. However, its performance under contemporary low X-ray frame and pulse rate settings is unknown. We aim to validate the feasibility and performance of quantitative flow ratio (QFR) and vessel fractional flow reserve (vFFR) under such angiograms.
Angiography-Derived Fractional Flow Reserve: Newer Data and …
2025年3月1日 · Murray fractal law‐based QFR (μQFR) (Pulse Medical Imaging Technology, Shanghai, China) is a method of obtaining QFR measurements using a single angiographic projection.
Coronary physiologic assessment based on angiography and …
2022年1月1日 · QFR consistently demonstrated excellent diagnostic accuracy in predicting the functional significance of coronary stenoses regardless of lesion length or various patient characteristics including sex, diabetes mellitus, and non …
Comparison of quantitative flow ratio and fractional flow reserve …
2019年11月19日 · Quantitative flow ratio (QFR) and fractional flow reserve (FFR) have not yet been compared head to head with perfusion imaging as reference for myocardial ischemia. We aimed to compare the diagnostic accuracy of QFR and FFR with myocardial perfusion scintigraphy (MPS) or cardiovascular magnetic resonance (CMR) as reference.
Percutaneous Intervention - Pie medical imaging
Percutaneous interventions are image guided. With our solutions you can examine the coronary and peripheral vessels. This can be done prior, during and after a procedure. We offer the following solutions:
Background and Objectives: Quantitative flow ratio (QFR) is an angiography-based technique for functional assessment of coronary artery stenosis. This study investigated the response of QFR to different degree of stenosis severity and its ability to predict the positron emission tomography (PET)-defined myocardial ischemia.
