The radiation dose and the amount of contrast media are the limitation of coronary CT angiography (CTCA). Low dose protocol of contrast media using 80kV has not been elucidated. We compared the radiation dose and image quality of the ultra-low dose protocol using 80kV and standard protocol ...

CT angiography can delineate multiple findings associated with graft stenosis and occlusion. Calcified and noncalcified atherosclerotic plaque is readily identified, and the calculation of the extent of graft narrowing is straightforward (Figure 6). Occlusion can be determined by nonvisualization of a ves...
CT Coronary Angiography Abstract Direct visualization of the epicardial coronary arteries is currently the reference standard to confirm the presence or focal severity of coronary luminal disease, or both. For more than 50 years1the coronary angiogram has been used to define epicardial coronary disease....

注:CCTA为冠状动脉CTA(Coronary CT Angiography) CT的优势及不足:CT具有空间分辨率高、成像速度快、覆盖范围大,处理后可进行任意切面的多平面成像和三维成像的特点,所以是显示心脏和大血管解剖的最佳方法,主要用于心血管疾病的解剖学评价。 CT的不足在于检查具有放射性,需要使用碘对比剂(碘过敏和肾功能不全为禁忌证...
