摘　　要：目的:探讨风湿性肺部病变HRCT表现的一般特征.材料和方法:分析308例风湿病的肺HRCT图像,观察病变的分布特点、肺与支气管病变的形态特点.结果:风湿性肺病的病变分布主要为周边分布(63.6%)、偏后侧分布(57.8%)及膈上肺底分布(61.4%).本组大多数肺部病变表现为磨玻璃影(68.9%)及线样结构(59.4%),部分病例可伴有网状改变或蜂窝影(32.2%)及界面征(34.1%).风湿病大支气管及小支气管的受累率分别为1.9%和32.5%(X2=96.54,P＜0.01).马赛克灌注的检出率在吸气、呼气相扫描上分别为15.3%、25.6%(X2=10.35,P＜0.01).结论:风湿性肺病HRCT表现有一定的特征.病变分布主要位于周边、偏后侧及膈上区域;肺部病变表现主要为磨玻璃影、线样结构、网状改变或蜂窝影及界面征等;支气管病变主要累及小支气管.Purpose:To evaluate the general features of HRCT in rheumatic lung diseases. Materials and Methods: 308 patients with rheumatic lung diseases were analyzed with HRCT images to describe the lesion distribution and manifestations. Results: The lesion distribution was mostly peripheral(63.6%), posterior (57.8%) and at the lung basement(61.4%). In this group, the images showed mostly ground-glass opacity(68.9%), linear pattern(59.4%), and partly reticular pattern and honeycombing(32.2%) and interface pattern(34.1%). The involvement rate of large bronchi and small bronchi were 1.9% and 32.5% respectively. The mosaic perfusion was found by 15.3% and 25.6% in inspiratory and expiratory scans accordingly. Conclusion: There are some general features in HRCT findings with rheumatic lung diseases. The lesion distribution is mostly peripheral, posterior and at the lung basement. The pulmonary manifestations are mainly ground-glass opacity, linear pattern, reticular pattern and honeycombing and interface pattern, et al. Small bronchi are more likely involved than large bronchi.
