摘要
目的 探讨非增强性螺旋CT扫描对肺动脉血栓栓塞的诊断价值。方法 对 2 1例经临床综合检查确诊的肺栓塞螺旋CT扫描资料进行回顾性分析。结果 2 1例患者CT扫描均有阳性发现 ,其敏感性为 10 0 %。其中诊断正确者 7例 ;误诊为胸腔积液合并肺炎者 9例 ;胸腔积液者 3例 ;机化性肺炎1例 ;周围型肺癌 1例。结论 CT平扫可提供肺栓塞存在与否的有力证据 ,是简便、安全、敏感的检查手段。提高对本病的警惕 。
Objective To investigate the diagnostic value of helical CT study in pulmonary thromboembolism with analysis on signs of plain CT images in particular.Method A retrospective analysis was made on 21 cases,whose data were studied previously with helical CT plain scanning.Results In all of the 21 cases there were positive findings on CT images(sensitivity,100%).Among them,7 cases were diagnosed correctly;9 cases were misdiagnosed as pleural effusion plus pneumonia;3 pleural effusion;1 organized pneumonia and 1 peripheral lung cancer.Conclusion Strong evidence of the disease can be given even with plain CT studies.The procedure is simple,safe and reliable.If CT is available at the hospital,it should be the first choice in the study provided that the disease is suspected.We should never put undue stress on the findings of a plain chest film.
