Hypertrophic cardiomyopathy (HCM) is a genetic cardiac disease. Its early detection is important because it is the most common cause of sudden cardiac death among young people. However, HCM is often a dilemma for clinicians because it manifests with diverse phenotypic expressions and clinical courses. With the advances in imaging technology, magnetic resonance (MR) imaging and multidetector computed tomography (CT) serve as suitable modalities for detecting and characterizing HCM and obtaining information for appropriate management of cases of HCM, although echocardiography is currently the most widely used modality. This article is an overview of the definition of HCM, its various phenotypes, risk stratification of HCM, and the potential application of cardiac MR imaging and multidetector CT for the assessment of HCM.
肥厚型心肌病（HCM）是一种遗传性心脏病。早期发现很重要，因为它是年轻人心脏性猝死的最常见原因。然而，HCM 常常是临床医生面临的难题，因为它表现出多种表型和临床病程。随着影像学技术的进步，磁共振（MR）成像和多排 CT（CT）成为检测和特征化 HCM 以及获取适当管理 HCM 病例信息的合适方式，尽管超声心动图目前是最广泛使用的方式。本文概述了 HCM 的定义、其各种表型、HCM 的危险分层，以及心脏 MR 成像和多排 CT 在 HCM 评估中的潜在应用。
