摘要
目的评价高分辨率CT(HRCT)在支气管扩张检查中的应用价值。资料与方法搜集临床可疑支气管扩张及常规CT扫描(层厚8mm)局部肺纹理增粗者64例,行HRCT扫描(层厚1mm)、大矩阵和高分辨率骨算法。结果常规CT可疑者HRCT清晰显示了支气管扩张的部位、类型和范围,可不同程度显示"双轨征"、"树芽征"、"指套征"及"印戒征"。64例中常规CT扫描诊断支气管扩张38例(88个肺段),其中柱状型23例,静脉曲张型3例,囊状型12例和混合型26例。HRCT诊断支气管扩张64例(198个肺段),其中柱状型33例,静脉曲张型8例,囊状型23例和混合型42例。结论HRCT诊断支气管扩张具有更高的敏感性、特异性及准确性,不仅能显示支气管扩张的范围、程度和部位,而且无创伤。可作为诊断支气管扩张的首选检查方法。
Objective To evaluate the value of High Resolution Computed Tomography（HRCT） in diagnosing bronchiectasis. Materials and Methods 64 patients with the clinical suspicion of bronchiectasis and routine CT scan with partial lung marking increased were carried on HRCT. Thin slice （ 1 mm）, big matrix with high resolution bone calculate way were used. Results The HRCT clearly showed bronchiectasis of part, type and scope which the routine CT suspected. HRCT could show the different degree of＂ the double track＂, ＂the sapling＂,＂ the fingerstall＂ ,＂ tag marking＂. The routine CT showed 38 cases of bronchiectasis with 88 lung segments in 64 patients ,which included cylindrical type in 23 cases,varicose type in 3 cases,saccular type in 12 cases,and mixed type in 26 cases. The HRCT revealed all 64 cases of bronchiectasis with 198 lung segments, which included cylindrical type in 33 cases, varicose type in 8 cases, saccular type in 23 ca- ses,and mixed type in 42 cases. Conclusion The HRCT scan has higher sensibility,specificity and accuracy for diagnosing bronchiectasis, and it can be used as the best choice of diagnosing bronchiectasis.
