目的探讨肺部CT增强及CT后处理技术在肺隔离症诊断中的价值。方法分析梅河口市医院2002-2007年间经手术及病理证实的肺隔离症10例,9例术前行胸部薄层增强CT检查并应用多平面重建、最大密度投影及曲面平展等多种后处理技术进行重建。结果9例行胸部薄层增强CT检查及应用多种后处理技术进行重建的病例中,8例发现异常血供,确诊率为89%。结论术前行胸部薄层增强C扫描T并应用多种后处理技术进行重建有利于发现异常血供,对肺隔离症诊断有重要价值。
Objective To investigate the value of pulmonary CT enhancement and CT post-processing in the diagnosis of pulmonary sequestration. Methods 10 cases of pulmonary sequestration confirmed by operation and pathology in Meihekou Hospital between 2002 and 2007 were analyzed retrospectively. Nine cases underwent preoperative thoracic thin layer contrast-enhanced computed tomography (CT) examination and applied various post-processing methods such as multiplanar reconstruction, maximum density projection and curved surface flattening Technology to rebuild. Results Of the 9 patients who underwent thoracic thin-slice enhanced computed tomography (CT) and reconstruction with various post-treatment techniques, 8 patients had abnormal blood supply, and the diagnosis rate was 89%. Conclusions The preoperative enhancement of C-scan of the thoracic lamina with multiple post-processing techniques is helpful for the detection of abnormal blood supply, which is of great value in the diagnosis of pulmonary sequestration.
