目的 研究电子束ＣＴ（ＥＢＣＴ）在心脏肿瘤诊断中的临床价值。方法 自１９９５年７月至１９９９年２月，行ＥＢＣＴ检查１２０２４例，共诊断心脏肿瘤４０例（占０．３３％）。本研究重点对有手术、尸检和临床随访结果的２２例进行回顾性分析。其中男１３例，女９例；年龄从５个月至７２岁，平均４１．９岁。１７例同时行单层增强和电影序列，３例单纯行单层增强，１例电影序列，１例单层平扫。结果 ２２个病例，ＥＢＣＴ均做出

Clinicalapplication of EBCT in the diagnosis of cardiac neoplasms

Objective To probe the clinical utilization of electron beam CT (EBCT)in the diagnosis of cardiac neoplasms Methods Between July 1995 and Feb 1999, EBCT was performed in 12 024 patients in our hospital. 40 (0 33%) patients were diagnosed as cardiac neoplasms Retrospective analysis of 22 patients confirmed by operation, autopsy or follow up was done In this group ,there were 13 males and 9 females, age ranged from 5 months to 72 years old ( averaged 41 9 years) 17patients had both contrast single slice mode(contrast SSM)and movie mode, 3 patients only SSM, 1 patient movie mode and 1 patient plain SSM Results Accurate localization and quantitative diagnoses were made in all the 22 patients and correct histopathological diagnosis was made in 10 patients with myxoma EBCT provided characteristic clues to proper histopathological determination in 6 of the 7 patients with non myxomous benign neoplasms In the 5 patients with malignant masses, 4 patients acquired distinct histopathological classifications,and involvement of the adjacent anatomic structures was revealed Conclusion Because of excellent temporal, spatial and density resolution, EBCT has not only high accuracy in the diagnosis of myxoma, but also possesses advantage superior to echocardiography in the definition of non myxomous benign and malignant neoplasms,which are diffcult to diagnose histopathologically using echocardiography EBCT is also valuable for assessment of involvement of neigbouring organs In the diagnosis of cardiac neoplasm without specific features, this method is limited and difficult
