目的 :评价HRCT在肺小支管扩张诊断中的价值。材料与方法 :对 4 8例临床怀疑为支气管扩张的患者分别进行常规螺旋CT扫描和深吸气及深呼气相HRCT扫描。将螺旋CT与HRCT扫描结果进行对照分析 ,找出HRCT在小支气管扩张诊断中的优势及深吸气与深呼气相HRCT的特点。结果 :4 8例患者中 ,螺旋CT发现支气管扩张 38例 ,深吸气HRCT发现支气管扩张 4 3例。同时 ,深呼气相HRCT能清晰的显示病变肺叶的空气潴留征。结论 :深吸气相HRCT扫描对诊断支气管扩张比常规CT有更大的优越性 ,对临床怀疑支气管扩张的患者 ,应首选HRCT检查。
Objective: To evaluate the value of HRCT in the diagnosis of pulmonary dilatation. MATERIALS AND METHODS: A total of 48 patients with suspected bronchiectasis were performed routine spiral CT scan and deep inspiration and deep expiratory HRCT scans respectively. The spiral computed tomography (CT) and HRCT scan results were compared to find out the advantages of HRCT in the diagnosis of bronchial dilatation and the characteristics of deep inspiration and deep expiration HRCT. Results: Of the 48 patients, spiral CT showed bronchiectasis in 38 cases, deep inspiration HRCT in 43 cases of bronchiectasis. At the same time, deep expiratory HRCT can clearly show signs of airway retention in diseased lungs. CONCLUSIONS: Deep inspiration HRCT is more effective in diagnosing bronchiectasis than conventional CT. HRCT should be the first choice in patients with clinical suspicion of bronchiectasis.
