胸部CT在不明原因咯血中的诊断价值

The Value of Computeriged Tomography in the Investigation of Unexplained Hemoptysis

为了解胸部ＣＴ在不明原因咯血中的诊断价值，对胸部Ｘ线片、痰找瘤细胞、痰找抗酸杆菌检查均阴性的咯血病人４０例，采用胸部ＣＴ自肺尖至膈顶连续扫描。结果：２６例（６５％）病人发现异常。其中支气管扩张１５例（３７．５％），肺炎４例（１０％），肺结核４例（１０％），肺囊肿３例（７．５％）。结果提示：不明原因咯血者以支气管扩张多见；

The purpose of this study is to evaluate the use of CT in the investigation of unexplained hemoptysis. Those patients who were diagnosed normal through chest radiographs and examinations of the sputum forcells and tubercle bacillus were studied by CT from lung apex to diaphragm . Abnormalities were seen in 26(65%) of the CT scans. Fifteen of the patients had evidence of bronchiectasis (37.5%). In four cases (10%) infiltrative pulmonary tuberculosis was detected. In four cases(10%) pneumonia was read and lung cysts were shown in the final three (7.5%). The results showed that CT scan can be used as a routine study for suspected hemoptysis and most of the unexplained hemoptysis cases are bronchiectasis, pulmonary tuberculosis and pneumonia.
