摘　　要：320排CT在心脏成像中,不仅能缩短扫描时间、减少造影剂的使用、降低射线曝光剂量、较少受快心率及心律不齐的影响;在评价心肌存活和心肌灌注等方面,320排CT也具有很好的应用前景。在本文中,我们将结合本院的初步应用经验和相关文献,试论述宽探测器320排CT与传统多排螺旋CT相比较所具有的优缺点,以及其在心脏检查方面新的应用。320-detector-row computed tomography provided many advantages over conventional multidetectorrow computed tomography（MDCT） for cardiac CT scanning, such as shortening the scanning time, reducing radiation and contrast agent dose and best imaging in the setting of arrhythmia or irregular heart rates. In addition, 320-slice MDCT also has a good application prospects in evaluating myocardial viability and myocardial perfusion, In this article, we reviewed the advantages and disadvantages of 320-slice MDCT compared with conventional MDCT, and discuss its new applications in the cardiac computed tomography.
