Abstract

Coronary artery calcification (CAC) is usually detected by fluoroscopy or on cine films during coronary angiography, but measurement of the calcification is not possible. Gated tomography of the heart provides a full sized image with high contrast spatial resolution of 0.1 mm and low contrast spatial resolution of 0.76 mm. The radiation exposure to the heart is between 1-5% of that experienced with coronary cinefluorography . Measurement of the diameter of calcium deposits is possible and calcium that could be related to arterial stenosis may be identified.

摘要

冠状动脉钙化（CAC）通常在冠状动脉造影期间通过荧光透视或电影胶片检测到，但钙化的测量是不可能的。心脏门控断层扫描可提供全尺寸图像，其高对比度空间分辨率为0.1毫米，低对比度空间分辨率为0.76毫米。心脏所受的辐射剂量是冠状动脉电影荧光造影的1%-5%。钙化沉积物的直径测量是可行的，并且可以识别可能与动脉狭窄相关的钙化。
