The introduction of digital subtraction angiography for the investigation of heart disease has lead to improved image contrast, with a marked reduction in radiation to patients, as compared with conventional radiography. Indications for ECG-triggered computed tomography of the heart in women should be strictly limited.
数字减影血管造影技术在心脏病检查中的应用提高了图像对比度，与传统放射成像相比，显著减少了患者所受辐射。女性患者进行心电图触发心脏计算机断层扫描的适应症应严格限制。
