CT examination of the thorax is often requested for the investigation of disorders that may have an important underlying cardiac cause or association that is not clinically obvious. Conditions such as idiopathic and acquired cardiomyopathy, ischemic heart disease, and valvular dysfunction may underlie symptoms such as dyspnea, chest pain, and hemoptysis that prompt the request for CT of the thorax. Other conditions such as pulmonary thromboembolic disease, chronic obstructive airways disease, pectus excavatum, sleep apnea, and many intrathoracic malignancies may have an important effect on cardiac structure and function. Patients undergoing thoracic surgery may have unsuspected coronary artery disease that can be detected in the course of preoperative evaluation by CT; similarly, postoperative complications often have a cardiogenic basis.
Examination of the heart in the course of CT of the chest often can provide important and clinically relevant information that is not otherwise easily available.
胸部CT检查常用于排查可能存在重要潜在心脏病因或关联但临床症状不明显的疾病。特发性和获得性心肌病、缺血性心脏病以及瓣膜功能障碍等疾病可能是导致呼吸困难、胸痛和咯血等症状的潜在病因，这些症状促使患者要求进行胸部CT检查。其他疾病，如肺血栓栓塞症、慢性阻塞性气道疾病、漏斗胸、睡眠呼吸暂停以及许多胸内恶性肿瘤，可能对心脏结构和功能产生重要影响。接受胸外科手术的患者可能存在术前CT评估未发现的冠状动脉疾病；同样，术后并发症往往也有心脏源性基础。
胸部CT检查过程中对心脏的检查通常能够提供重要且与临床相关的信息，而这些信息通过其他方式不易获取。
