摘要目的评价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例非包裹性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%,准确性为87%.结论 CT胸腔造影检查在胸膜病变的检出及良恶性病变的鉴别诊断方面明显优于常规CT检查.

abstractsObjectives　To evaluate the ability of CT pleurography (CTP) in detecting minor pleural lesions in patients with pleural effusion and to assess its value in distinguishing malignant from benign pleural lesions. Methods　A prospective study of 50 patients with pleural effusion was conducted using conventional CT and CTP. CT scan was run after injecting an appropriate amount of contrast medium into the pleural cavity. Results　In 24 patients, all lesions detected by conventional CT were demonstrated by CTP. In 13 of 24 patients, CT pleurography detected additional lesions. In 20 of 26 patients with negative findings on conventional CT, CTP 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 CTP, respectively. Conclusion　CTP is superior to conventional CT in detecting and for the differential diagnosis benign and malignant pleural lesions.
