MSCT技术的飞速进步使得非侵入式冠状动脉CT成像的图像质量不断提高。64层螺旋CT在冠状动脉疾病(CAD)的诊断上已相当准确[1~6],尤其其阴性预测值极高,即非侵入式MSCT冠状动脉血管成像正常基本可除外CAD的诊断。但对于高心率或心律不齐的病人只有时间分辨率100 ms时图像质量才?
The rapid advances in MSCT technology have led to the continuous improvement of image quality in noninvasive coronary CT imaging. 64-slice spiral CT has been fairly accurate in the diagnosis of coronary artery disease (CAD) [1-6]. In particular, the negative predictive value is very high, ie non-invasive MSCT coronary angiography can be diagnosed except CAD. But for patients with high heart rate or arrhythmia only the temporal resolution of 100 ms when the image quality?
