螺旋CT增强扫描对于中央型肺癌的诊断价值分析

The Diagnostic Value of Spiral CT Enhanced Scan in Central Type of Lung Cancer

目的探讨螺旋CT增强扫描在诊断中央型肺癌病例中的价值。方法选取2013年12月至2015年12月在我院进行诊断治疗且经手术病理确诊为中央型肺癌的84例患者为研究对象,将这些患者首先根据肿瘤期分为四组,每组除了几例患者使用平扫外,其余都进行螺旋CT增强扫描,将螺旋CT增强扫描的结果与常规手术病理的诊断结果进行比较并作出分析。结果螺旋CT增强扫描能有效地区分出中央型肺癌肿块与肺不张,每组肺癌患者的CT扫描结果与其手术病理诊断结果的符合率分别为83%、81%、80%以及85.7%,总体符合率为82.4%,误诊病例皆为未接受CT增强扫描患者。结论螺旋CT增强扫描可以对肺门结构、胸膜侵犯等症状给出较为准确的判断,该技术对提高中央型肺癌的术前诊断有着很大的意义。

Objective To explore the application value of spiral CT（SCT） enhanced scanning in the diagnosis of central lung cancer. Methods Eighty-four cases who were pathologically confirmed central lung cancer from December 2013 to December 2015 in our hospital were chosen as the object of study, and they were divided into four groups according to tumor stage. Except for a few patients examined by plain scan, the rest had spiral CT enhanced scan, the results of it were compared to and pathologic diagnosis after conventional surgery. RReessuullttss Spiral CT can effectively distinguish central lung mass from atelectasis, while the coincidence rate of surgical pathology in each group was 83%,81%, 80% and 71.4%, and total coincidence rate was 78.3%. The misdiagnosed cases are all patients who did not receive enhanced CT scan. CCoonncclluussiioonn Spiral CT enhanced scan can show hila structures, pleural assault clearly. It has great significance to help the diagnosis of central lung cancer before operation.
