胸部高分辨率CT与支气管造影术在诊断支气管扩张症中的对比研究

A Comparative Study of HRCT and Bronchography in Diagnosis of Bronchiectasis

目的：评价非创伤性HRCT诊断支气管扩张的价值。材料与方法：对300例临床拟诊为支气管扩张症的病人进行HRCT检查，其中120例进行了支气管造影检查，对二种方法检查结果进行对照研究。结果300例患者中HRCT均呈现不同类型的支气管扩张表现，其诊断准确性为100％，而支气管造影术为85％。结论：HRCT能够明确支气管扩张的部位和程度，其诊断敏感性明显高于支气管造影术，它是一种安全、简便、可靠的检查手段。

Purpose: To eva1uate the role of HRCT in diagnosis of bronchiectasis. Materials and Methods: 3oo cases clin1cally suspected of bronchiectasis were examined by HRCT. l2O cases had bronchography for comparison. Rosults: 3oO cases of bronchietasis were visualized in HRCT. The accuracy in determining the nature of bronchietasis was 1oo % and tbe bronchography was 85 %. Conclu' sion: HRCT could demonstrate thc site and extent of bronchietasis. Thc sensitivity of HRCT is higher than bronchography. It is a safc, simple and reliable method.
