目的:分析原发性心脏非粘液瘤性肿瘤的影像学特征,评估几种常用的影像学诊断方法的主要优势及局限性。方法:搜集1979年1月至2004年3月来有完整临床、影像学及病理资料证实的原发性非粘液瘤性心脏肿瘤65例, 其中接受电子束计算机断层摄影术(EBCT)检查23例,磁共振成像(MRI)检查19例。结果:X线胸片示异常50例,超声心动图(UCG)诊断敏感性86.15%(56/65),EBCT和MRI所有肿瘤均检出,部分诊断与手术病理结果一致。结论:X线胸片适合做常规检查,UCG可做首选初查且对心腔或心包腔内的肿瘤诊断准确率高;EBCT或(和)MRI 能从肿瘤大小、形态甚至组织学特征如脂肪、纤维、出血、囊肿、钙化等全面评价肿瘤,做出诊断与鉴别诊断。
OBJECTIVE: To analyze the imaging features of primary cardiac non-myxomatous neoplasms and to evaluate the main advantages and limitations of several commonly used diagnostic imaging modalities. Methods: Sixty-five patients with primary non-myxomatous heart tumors confirmed by complete clinical, radiological and pathological data from January 1979 to March 2004 were collected. Twenty-three patients underwent electron beam computed tomography (EBCT) , Magnetic resonance imaging (MRI) examination in 19 cases. Results: X-ray showed 50 cases of abnormalities, the diagnostic sensitivity of echocardiography (UCG) was 86.15% (56/65), all the tumors were detected by EBCT and MRI, and some of the diagnosis was consistent with the pathological findings. Conclusions: X-ray is suitable for routine examination. UCG can be the first choice for initial examination and has high accuracy in diagnosing the heart cavity or pericardial cavity. EBCT or MRI can distinguish tumor from size, shape and even histological features such as fat , Fiber, hemorrhage, cysts, calcification and other comprehensive evaluation of the tumor, make a diagnosis and differential diagnosis.
