%X 心脏肿瘤是一类罕见的实体肿瘤，其缺乏典型的临床表现，常因出现胸闷、气喘等非特殊症状来就诊。虽然超声心动图是检测心脏肿瘤的首选，但其真阳性率和敏感性较低。计算机断层扫描技术对心脏肿瘤存在钙化时具有很高的敏感性，但存在不能实时动态成像及对比度不足等局限性。随着心血管磁共振(Magnetic Resonance Imaging, MRI)成像诊断技术的发展，使用MRI检测心脏肿瘤已成为现实并逐渐成为重要检查依据。MRI检查的特点主要是对心脏软组织分辨率较高，能实现横断面、失状面、冠状面多方位成像，并通过后处理技术针对心脏肿瘤进行立体成像，为临床提供更丰富更全面的诊断信息，有效提高相关疾病的识别及鉴别能力。本文将对近年来MRI用于诊断心脏肿瘤的图像特点进行梳理汇总，旨在更好地为临床对心脏肿瘤的早诊断早治疗提供帮助。<br />
Cardiac tumor is a rare solid tumor, which lacks typical clinical manifestations, and patients often come to a doctor for non-special symptoms such as chest tightness and asthma. Although echocar-diography is the first choice for detecting cardiac tumors, its true positive rate and sensitivity are low. Computed tomography has a high sensitivity for calcification in cardiac tumors, but it has limi-tations such as inability to real-time dynamic imaging and insufficient contrast. With the develop-ment of cardiovascular magnetic resonance imaging (Magnetic Resonance Imaging, MRI) imaging diagnostic technology, the use of MRI to detect cardiac tumors has become possible and has gradu-ally become an important examination basis. MRI examination is mainly characterized by high res-olution of cardiac soft tissue, which can achieve multi-directional imaging in cross-section, loss-of-shape and coronal plane, and three-dimensional imaging of cardiac tumors through post- processing technology, which can also provide richer and more comprehensive diagnostic infor-mation for the clinic through post-processing technology for stereoscopic imaging of cardiac tumors, which can effectively improve the diagnosis and differential diagnosis capabilities of related dis-eases. This article will summarize the image characteristics of MRI used in the diagnosis of cardiac tumors in recent years, aiming to better help the clinic to provide assistance for the early diagnosis and early treatment of cardiac tumors.
