Blood Vessel Segmentation and shape analysis for quantification of Coronary Artery Stenosis in CT Angiography
… for quantitative vascular shape analysis of the coronary arteries, which constitutes an important and fundamental component of an automated image-based diagnostic system. Firstly, an automated vessel segmentation algorithm is developed to extract the coronary arteries based on the framework of …

Relationship Between Intravascular Ultrasound Parameters and Fractional Flow Reserve in Intermediate Coronary Artery Stenosis of Left Anterior Descending Artery
… FFR were performed in 206 cases of intermediate stenosis of the left anterior descending artery (LAD). Myocardial ischemia was assessed by FFR and maximal hyperemia was induced by continuous intracoronary adenosine infusion. FFR < 0.80 was considered as significant inducible myocardial ischemia. …

Vergleich der Perfusionsdiagnostik mittels Magnetresonanztomographie mit dem invasiv bestimmten hämodynamischen Schweregrad von Koronarstenosen zur Detektion der hämodynamischen Relevanz von Stenosen der Koronararterien
… great promise for the detection of significant coronary artery disease (CAD). This study evaluated whether FP-CMR could predict the hemodynamic significance of epicardial coronary artery stenosis as defined by invasively determined fractional flow reserve at coronary angiography. All patients …

Association of Metabolic Syndrome and Smoking with Coronary Artery Calcification in Health Screen Examiness of men
Coronary artery calcification Score, which is an indicator to predict coronary artery stenosis, has been known to be an independent risk factor of occurrence in ischemic heart disease while it has been reported that metabolic syndrome increased the risk of coronary heart disease and its mortality …

Comparison of clinical outcome after revascularization versus conservative treatment in patients with borderline fractional flow reserve measurements
… tool for assessing the functional severity of coronary artery stenosis and for clinical decision of treatment strategy. Many studies have shown that FFR measurement <0.75 is specific for ischemia, but there is a controversy about whether we need to intervene the lesion of FFR measurement …

Bedeutung des Volume Rendering in der Diagnostik der Koronargefäße mittels Mehrschichtspiral-CT
… rendering techique (3D-VRT) to quantitative coronary angiography (QCA) and on the other hand to challenge the diagnostic value of 3D-VRT. For 53 patients (42m, 11f), retrospectively ECG-gated MSCT of the heart was performed as well as quantitative X-ray coronary angiography. The standardized …
