CT胸腔造影检查及其临床应用

目的 评价ＣＴ胸腔造影检查在胸膜病变诊断中的作用。方法 应用ＣＴ胸腔造影检查对５０例非包生胸腔积液病人进行前瞻性研究。结果 ２４例常规ＣＴ所显示的病灶ＣＴ胸腔造影检查均能显示，其中１３例检出了更多的病灶；２６例常规ＣＴ显示阴性者中２０例ＣＴ胸腔造影检查检出病灶。常规ＣＴ检出胸膜病变的敏感性为２５％，特异性为１００％，准确性为３０％；胸腔造影检查检出胸膜病变的敏感性为８６％，特异性为１００％，准确性

Evaluation of CT pleural contrast examination

Objective To evaluate the ability of CT pleurography (CTP) in detection and diagnosis of pleural diseases. Methods A perspective study of 50 patients with pleural effusion was conducted using conventional CT and CTP. Results In 24 cases all the lesions detected by conventional CT, were demonstrated by CT pleurography. In 13 of the 24 cases, CT pleurography detected additional lesions. In 20 of 26 cases with negative finding on conventional CT, CT pleurography was capable of demonstrating the presence of pleural lesions. The sensitivity, specificity and accuracy of detecting pleural lesions were 25%, 100% and 30% for conventional CT, 86%, 100% and 87% for CT pleurography. ConclusionsZCTP is superior to conventional CT in detecting and differential diagnosis of benign and malignant pleural diseases.
