目的 :分析心脏心包非粘液瘤性原发性肿瘤磁共振成像 (MRI)的影像学特征 ,评估其临床价值。 方法 :收集经手术病理证实的原发性非粘液瘤性心脏心包肿瘤 14例 ,行 MRI自旋回波多体位扫描及磁共振电影检查。 结果 :14例 MRI所见肿瘤部位、大小、扩展范围与外科和 (或 )大体病理所见几近一致 ,其中 9例定性诊断正确 ,包括脂肪瘤 3例、纤维瘤 2例和心包囊肿伴出血 4例。 结论 :MRI软组织分辨率高 ,其大视野更有助于显示肿瘤与周围结构 (如纵隔、肺和膈肌等 )的关系 ;MRI电影则可补充一些解剖资料 ,显示血流动态变化。同时 MRI尚有助于对脂肪瘤、纤维瘤和心包囊肿伴出血等做出初步的定性诊断。
Objective: To analyze the imaging features of magnetic resonance imaging (MRI) of non-myxomatous primary tumor in cardiac pericardium and evaluate its clinical value. METHODS: Fourteen cases of primary non-myxomatous cardiac pericardial tumors confirmed by pathology were collected for MRI spin echo multiple-position scans and magnetic resonance imaging examinations. Results: The tumor site, size, and extension range seen in MRI were similar to those seen by surgery and/or gross pathology in 14 cases. Among them, 9 were diagnosed qualitatively, including 3 lipomas, 2 fibroids, and pericardial cyst with hemorrhage. 4 cases. Conclusion: MRI soft tissue has high resolution, its large field of view is more helpful to show the relationship between tumor and surrounding structures (such as mediastinum, lung and diaphragm), and MRI film can add some anatomical data to show the dynamic changes of blood flow. At the same time MRI still help to make a preliminary qualitative diagnosis of lipoma, fibroids and pericardial cysts with bleeding.
