| 摘 要： | 目的探讨结缔组织病肺间质病变致肺动脉高压的多层螺旋CT诊断价值。方法收集经临床确诊为结缔组织病、且怀疑伴有肺动脉高压患者60例,每位患者均给予DR胸片、彩色多普勒超声及多层螺旋CT下高分辨率CT检查。以主肺动脉直径大于29mm、主肺动脉直径与降主动脉直径比值大于1作为多层螺旋CT诊断肺动脉高压的依据,与相应DR胸片及彩色多普勒超声诊断肺动脉高压比较。结果多层螺旋CT诊断肺动脉高压42例（42/60）与相应DR胸片诊断肺动脉高压37例（37/60）及彩色多普勒超声诊断肺动脉高压44例（44/60）具有很好的一致性（Kappa≥0.75）,差异无统计学意义（P〉0.05）。结论多层螺旋CT能明确诊断结缔组织病肺间质病变致肺动脉高压,同时能提供肺间质病变的信息,具有很好的临床价值。

| Abstract: | Objective To investigate the clinical diagnosis value of pulmonary hypertension(PH) caused by connective tissue diseases(CTD) with lung interstitial disease by HRCT. Methods 60 patients were involved in this study and were all underwent HRCT, chest X-ray, and color Doppler ultrasound examinations. PH was diagnosed if pulmonary artery diameter was larger than 29 mm,or the ratios of pulmonary artery trunk and ascending aorta diameter was larger than 1 in axial HRCT scan. Using chi square test, PH diagnosed or... |
