Arrhythmogenic right ventricular dysplasia (ARVD) is a heart muscle disorder characterized pathologically by fatty or fibrofatty replacement and electrical instability of the right ventricular myocardium. This cardiac entity leads to sudden cardiac death, syncope, recurrent ventricular tachycardia, and in some cases, heart failure in a younger population. Contrast angiography, echocardiography, radionuclide angiography, ultrafast computed tomography (CT), and cardiovascular magnetic resonance imaging are techniques used to diagnose functional and morphologic characteristics of the disease. CT is sensitive in detecting intramyocardial fat because of its low attenuation. Recently the advances in multislice CT (MDCT) have improved temporal resolution, which has increased effectiveness in providing morphologic and functional information. We present a case with ARVD evaluated through 16-row MDCT. Fatty infiltration was clearly demonstrated by 16-slice CT; thus, multislice CT may have a significant role in the assessment and follow-up of patients with ARVD.
致心律失常性右室心肌病（ARVD）是一种心肌疾病，其病理特征为右心室心肌的脂肪或纤维脂肪替代以及电不稳定。这种心脏疾病会导致年轻人群发生心源性猝死、晕厥、反复发作的室性心动过速，在某些情况下还会导致心力衰竭。对比血管造影、超声心动图、放射性核素血管造影、超速计算机断层扫描（CT）和心血管磁共振成像都是用于诊断该疾病功能和形态特征的技术。CT因其低衰减在检测心肌内脂肪方面很敏感。最近多层螺旋CT（MDCT）的进展提高了时间分辨率，这在提供形态和功能信息方面提高了有效性。我们展示了一例通过16排MDCT评估的ARVD病例。16层CT清楚地显示了脂肪浸润；因此，多层螺旋CT在ARVD患者的评估和随访中可能具有重要作用。
