Although not considered a first-line modality for assessing cardiac masses, computed tomography (CT) can provide clinically useful information and is underused for this purpose. In addition to characterizing masses with insights about presence of fat or calcification and the perfusion characteristics of a mass, CT produces high-resolution four-dimensional images depicting the mass and its relationship to chambers, valves, and coronaries. This is combined with imaging of the chest, abdomen, or coronaries. Advances in CT technology, such as dual-energy CT, dynamic perfusion imaging, and three-dimensional printing for preoperative planning, will increase the role of CT in assessment of cardiac masses.
尽管计算机断层扫描（CT）不被视为评估心脏肿块的一线检查方法，但它能够提供具有临床实用价值的信息，且在这方面未得到充分利用。除了通过了解脂肪或钙化的存在以及肿块的灌注特征来对肿块进行特征描述外，CT还能生成高分辨率的四维图像，描绘肿块及其与心腔、瓣膜和冠状动脉的关系。这与胸部、腹部或冠状动脉的成像相结合。CT技术的进步，如双能CT、动态灌注成像以及用于术前规划的三维打印，将提升CT在心脏肿块评估中的作用。
