目的探讨128层螺旋CT成像技术在肺不张及其病因的诊断价值。方法将本院2012年6月~2013年5月收治的30例怀疑有肺不张患者作为研究对象,所有患者前期均先进行128层螺旋CT检查后再进行纤支镜检查,利用MSCT图像后处理技术对患者的肺不张形态、范围、周围结构等情况进行分析,并分析其病因。对比分析128层螺旋CT诊断结果与纤支镜、手术及病理检查结果 ,评价128层螺旋CT诊断肺不张及其病因的准确性。结果 30例患者均进行手术治疗,术中明确诊断,与影像诊断符合率为100%。经统计分析显示,128层螺旋CT检查与纤支镜、病理检查及手术符合率为100%。结论 128层螺旋CT成像可通过MSCT图像后处理技术了解肺不张患者的肺不张形态、范围、周围结构等情况,且可分析出引起肺不张的支气管管腔闭塞或狭窄的部位、狭窄程度,有无异物等情况,具有重要的诊断价值。
Objective To investigate the diagnostic value of 128-slice spiral CT imaging in atelectasis and its etiology. Methods Thirty patients with suspected atelectasis who were admitted to our hospital from June 2012 to May 2013 were enrolled in this study. All patients were examined with 128-slice spiral CT and followed by MSCT Treatment of patients with atelectasis of the lung shape, scope, the surrounding structure, etc. were analyzed and analyzed the etiology. The diagnostic results of 128-slice spiral CT and the results of fiberoptic bronchoscopy, surgery and pathology were compared and analyzed, and the accuracy of 128-slice spiral CT in the diagnosis of atelectasis and its etiology was evaluated. Results All the 30 patients underwent surgical treatment. The diagnosis was clearly confirmed in the operation. The coincidence rate with imaging diagnosis was 100%. The statistical analysis showed that 128-slice spiral CT examination with bronchoscopy, pathology and surgery in line with the rate of 100%. Conclusions 128-slice spiral CT imaging can be used to understand the atelectasis, extent and surrounding structures of atelectasis patients by MSCT image postprocessing technique and to analyze the site of bronchial lumen occlusion or stenosis that causes atelectasis. The stenosis Degree, with or without foreign body, has important diagnostic value.
