Multidetector computed tomography (MDCT) can play a role in diagnosis of coronary artery disease and in the assessment of left ventricle (LV) and right ventricle global function, with initial good correlation results with standard modalities. With the latest scanners, regional LV contractility with both qualitative and quantitative assessment has become possible. MDCT function evaluation by specific postprocessing software can be performed considering simultaneously different parameters plus the subjective visual perception of anomalies on 2-dimensional and 3-dimensional cine-loop models. MDCT's ability to make high-resolution 3-dimensional reconstructions throughout the cardiac cycle allows this imaging modality to evaluate both coronary and LV anatomy and morphology, and also LV functional parameters. The ability to provide functional information of the right ventricle represents another important application of MDCT both in patients with acute pulmonary embolism and with congenital cardiovascular disease. Initial results on accuracy are promising and the clinical applicability of MDCT should rapidly increase.
多排螺旋计算机断层扫描（MDCT）在冠状动脉疾病的诊断以及左心室（LV）和右心室整体功能的评估中发挥着作用，其初步结果与标准检查方法具有良好的相关性。借助最新的扫描仪，对左心室区域收缩功能进行定性和定量评估已成为可能。通过特定的后处理软件，可以在考虑不同参数的同时，结合二维和三维电影环模型上对异常情况的主观视觉感知，来进行MDCT功能评估。MDCT在整个心动周期进行高分辨率三维重建的能力，使这种成像方式能够评估冠状动脉和左心室的解剖结构及形态，以及左心室功能参数。提供右心室功能信息的能力是MDCT在急性肺栓塞和先天性心血管疾病患者中的另一重要应用。初步的准确性结果很有前景，MDCT的临床适用性应会迅速提高。
