When the ACQ severity is more than 50%, the visual method tends to overestimate the severity of the lesion.Conclusions: Our results suggest that for accurate estimation of a lesion severity, we need to use quantitative coronary angiography. Visual estimation has a significant bias and hence we ...

This secondary analysis of a randomized clinical trial examines whether immediate coronary angiography after out-of-hospital cardiac arrest with a
Quantitative Coronary Angiography The degree of coronary stenosis is quantitated from the cineangiogram and, in clinical practice, is usually a visual estimation of the percentage of diameter narrowing using the presumed proximal normal arterial segment and the ratio of the stenosis diameter to the nor...
B, Conventional invasive coronary angiogram showing the lumen indentation caused by plaque impingement (arrowhead). However, quantitative coronary angiography did not identify significant (>50%) lumen narrowing. AP indicates anterior-posterior. Bland-Altman Analysis of Stenosis Grading Using Multislice ...
A total of 91 consecutive patients underwent both low-dose 64-slice CT calcium scoring scan as well as conventional angiography of the heart. The total CCS of abnormal coronary angiogram (n = 45) was 297.38 +/- 416.93, whereas that of normal coronary angiogram (n = 46) was 5.37 +/- ...
自2015年11月至2017年8月于心内科招募已行冠脉造影(Coronary angiography,CAG)指导冠脉支架植入的症状性冠心病患者44例。本研究已通过临床伦理委员会审批,招募的患者均已签署知情同意书。按已经制定的入选标准排除严重肾衰竭、血管炎、心肌炎和转移性恶性肿瘤患者12例。最终确定32例患者被纳入本研究,其中男性22例、女性...
Freeze frames from cine loops obtained during invasive coronary angiography were used for the analysis of the left anterior descending (LAD), left circumflex (LCX), and right coronary artery (RCA). Assessment of coronary arteries was performed from two-dimensional angiograms. The left anterior ...
coronary angiography print; hidden biometric; filtered LBP; NCA; biometrics1. Introduction A coronary angiogram is one of the X-ray imaging techniques [1,2]. Coronary angiography is the gold standard diagnostic method of coronary artery disease (CAD) and CAD is the disease that causes the most...
