摘　　要：目的评价高分辨率ＣＴ（ＨＲＣＴ）在肺段水平对支气管扩张症（支扩）的诊断价值。方法对２９例临床诊断为支扩症的患者共５２２个肺段分别行ＨＲＣＴ及数字减影支气管造影（ＤＳＢ）检查。结果ＨＲＣＴ与ＤＳＢ对支扩诊断具有良好的一致性；以ＤＳＢ作为诊断金标准，ＨＲＣＴ显示支扩的灵敏度为９４％，特异度为９８％；假阳性率为４％，假阴性率为１％；支扩的ＨＲＣＴ表现主要为柱状和囊状扩张。结论ＨＲＣＴ较支气管造影具有更大的优越性；对临床疑为支扩的患者，应首选ＨＲＣＴ。Objective To assess the value of HRCT in the diagnosis of bronchiectasis at segmental level. Methods 29 cases (522 segments) with bronchiectasis doubted by clinical evaluation were selected and HRCT scan and digital subtraction bronchography (DSB) were performed. Results HRCT and DSB showed a good identity in the diagnosis of bronchiectasis. Of 92 segments diagnosed as bronchiectasis in HRCT, 84 were agreed with DSB; Of 430 segments diagnosed as no bronchiectasis by HRCT, 425 were agreed with DSB. Sensitivity of HRCT is 94%, specificity is 98%. The main HRCT findings were cylindric and cystic bronchiectasis. Conclusions HRCT is superior to bronchography for bronchiectasis. It is the first choice of the image diagnostic modalities for the patients in whom bronchiectasis is suspected.
