What is a CT Coronary Angiogram CT scans have been used to look at various anatomic regions, but have not been useful for the heart because the heart is continuously in motion. CT is very effective in looking at “static” areas, such as the brain, abdominal cavity, and extremities. Most...

本研究通过对比常规冠状动脉造影(conventional coronary angiogram,CCA),利用西门子128层螺旋CT冠脉成像研究冠心病患者临床心功能的分级与患者自身冠状动脉狭窄程度和狭窄数目的相互关系。 材料与方法 一 研究对象与方法研究对象:本研究选取自2008年9月至2011年10月本院行冠脉CT成像患者。选入标准:年龄范围在40-75岁间,...
Invasive coronary angiogram rates were 45.8%, 39% and 34.2% across the cohorts. 29.6% underwent revascularisation in cohort 1, 15.9% in cohort 2 and to 16.4% in cohort 3. Conclusions Increased CTCA availability was associated with a significantly reduced length of stay both pre-COVID-19 ...
A cardiac computerized tomography (CT) scan – which can also be referred to as a coronary CT angiography or CT angiogram – is an imaging test to view the heart and blood vessels. It is a test that carries few risks and is less invasive than alternative procedures such as an angiogram....
0626T Intraprocedural coronary fractional flow reserve (FFR) with 3D functional mapping of color-hyphencoded FFR values for the coronary tree, derived from coronary angiogram data, for real-hyphentime review and interpretation of possible atherosclerotic stenosis(es) intervention (List separately in addi...
近年来,冠状动脉CT血管成像(coronary CT angiography,CCTA)技术日臻成熟,高性能的成像设备使得冠状动脉清晰成像成为可能,CCTA正在成为无创诊断冠心病的重要方法.对比常规 导管法冠状动脉造影,CCTA能无创提供冠状动脉病变与否的证据,更容易被广大患者所接受.然而,现阶段CCTA具有阴性预测值高、阳性预测值低、时间分 辨率低以...
computationally-generated synthetic vascular trees to represent coronary vasculature below the resolution of the imaging and lumped parameter descriptions of systemic circulation, including the four heart chambers (Fig.2d). This resulted in multiscale models of coronary circulation for each patient, which ...
Is there an alternative to an angiogram? An alternative test,cardiac catheterization with a coronary angiogram, is invasive, has more complications related to the placement of a long catheter into the groin or wrist arteries extending all the way to the heart, and the movement of the catheter ...
