摘要
目的 :探讨改良式动态增强CT扫描对胸部病变诊断的价值。方法 :搜集连续胸部改良式CT增强扫描的病例 12 5例。所有病例在正位定位像上可发现明显的病变。全胸增强扫描前均在病灶中心层面平扫 1～ 3层 ,增强螺旋扫描后再在病灶相应层面加做延迟 2～ 5min的扫描。分析胸部病变改良式动态增强的CT诊断结果 ,与病检结果进行对照 ,以及改良式动态增强CT扫描对胸部病变诊断的价值。结果 :CT诊断的 12 5例病例 ,除 4例肺癌无法获得病检外 ,116例诊断正确 ,另 5例误诊。误诊主要在于病变自身特殊的病理结构所致 ,而与使用的这种增强扫描方法关系不大。结论 :胸部改良式动态增强CT扫描对胸部病变的正确诊断有很大帮助 。
Objective:To study the diagnostic value of a modified dynamic enhanced CT scans for chest diseases.Methods:A consecutive series of 125 patients was collected.Obvious lesions in all 125 cases were found on the orientation scanning.Before the enhanced CT scanning in the whole chest,one to three plain scans were obtained,then two to five minutes delayed scans at the level of the lesions were added to.CT findings by modified scanning technique were analyzed and correlated to the pathology.Results:Correct diagnosis using modified technique was made in 116 of 125 cases.Only 5 cases were misdiagnosed except 4 without pathological confirmation.Conclusion:Modified dynamic enhanced CT scanning technique is helpful and practical in the diagnosis of chest diseases.
