摘要
目的 :观察慢性梗阻性肺气肿的HRCT表现。材料和方法 :对 67例确诊为慢性梗阻性肺气肿患者 ,行全肺HRCT扫描。观察并分析肺气肿的CT表现形式及其分布。结果 :慢性梗阻性肺气肿的HRCT有 4种表现形式 ,即小叶中心型肺气肿 (CLE)、全小叶型肺气肿 (PLE)、间隔旁型肺气肿 (PSE)和混合型肺气肿 ,其中以PLE最为常见 ( 3 9/ 67,5 8.2 % )。CLE多见于上肺区且多见于吸烟者 ( 5 / 6)。有吸烟史和无吸烟史之间、男女之间肺气肿的形态学构成比差别都有高度的显著性。结论 :症状性慢性梗阻性肺气肿的HRCT形态以PLE最为常见。
Purpose: To assess utility of HRCT for detecting chronic obstructive emphysema(COE). Materials and Methods: 67 patients with COE underwent chest HRCT scan. The types and distribution of the emphysema on HRCT were evaluated. Results: Four types of COE were recognized: centrilobular emphysema(CLE),panlobular emphysema(PLE),paraseptal emphysema(PSE) and mixed emphysema. 58.2% of 39/67 cases were found in PLE .PLE was the most common type. CLE were observed with a significant predominance in the upper lung zones and smokers(5/6). High significant differences between smokers and nonsmokers(χ 2=70.1, p<0.01), male and female(χ 2=73.1, p<0.01, were observed with HRCT in the constituent ratio of the types. Conclution: On HRCT, the most common type of symptomatic COE is PLE.
