Multidetector-row computed tomography (MDCT) plays an essential role in oncologic imaging as the modality of mapping out the treatment strategy at staging, assessing response to the treatment, and following up patient outcome after the treatment. Even without electrocardiogram gating, MDCT provides accurate information about the heart. In the group of oncologic patients, different tumoral and non-tumoral-related heart disorders can be found, for example, metastatic cardiac involvement (approximately 10% of patients with lung or breast cancer will develop metastases to the heart), paraneoplastic cardiac disorders, non-tumor-related heart disorders, and chemotherapy- and radiotherapy-related cardiac side effects. MDCT plays a role in the detection of these entities. We show the non-electrocardiogram-gated MDCT findings of oncology-related cardiac disorders to encourage radiologists to recognize and report cardiac findings in oncologic patients. Appropriate knowledge of tumoral and non-tumoral-related MDCT features allows a complete evaluation of oncologic patients with ancillary cardiac findings. An adequate knowledge of the patient's medical history, previous treatments, and concomitant illnesses is essential to interpret heart findings in oncologic patients who undergo MDCT.
多排螺旋计算机断层扫描（MDCT）在肿瘤成像中起着至关重要的作用，它可用于制定分期治疗策略、评估治疗反应以及跟踪治疗后的患者预后。即使不进行心电图门控，MDCT也能提供有关心脏的准确信息。在肿瘤患者群体中，可发现不同的肿瘤及非肿瘤相关心脏疾病，例如，心脏转移（约10%的肺癌或乳腺癌患者会发生心脏转移）、副肿瘤性心脏疾病、非肿瘤相关心脏疾病以及化疗和放疗相关的心脏副作用。MDCT在这些疾病的检测中发挥着作用。我们展示了与肿瘤相关心脏疾病的非心电图门控MDCT表现，以鼓励放射科医生识别并报告肿瘤患者的心脏表现。对肿瘤及非肿瘤相关MDCT特征的适当了解有助于对伴有心脏相关表现的肿瘤患者进行全面评估。充分了解患者的病史、既往治疗情况及伴随疾病对于解读接受MDCT检查的肿瘤患者的心脏表现至关重要。
