摘要
本文旨在分析多层螺旋计算机断层扫描(MSCT)胸部平扫与增强扫描在判断肺部结节性质中的差异。回顾性分析125例肺部结节患者的临床资料及MSCT胸部平扫和MSCT增强扫描图像,对MSCT平扫和MSCT增强扫描下肺部结节图像进行分析。结果显示,增强扫描下分叶征、胸膜牵拉征、血管集束征、空泡征显示率均显著高于MSCT平扫(P<0.05)。良性结节病灶的增强CT值和CT值增量[分别为(56.84±11.36)Hu和(25.67±13.65)Hu]低于恶性结节病灶[分别为(79.52±12.32)Hu和(48.95±12.35)Hu,P<0.05]。MSCT平扫诊断灵敏度、特异度和准确度分别为65.96%、67.95%和67.20%,MSCT增强扫描诊断灵敏度、特异度和准确度分别为80.85%、80.77%和80.80%,MSCT增强扫描与病理结果更为接近。MSCT平扫与MSCT增强扫描对肺部结节性质的判断均具有较好的临床价值,但MSCT增强扫描对肺部结节性质的诊断价值更为突出。
The purpose of this paper was to analyze the difference between the multi-slice spiral computed tomography(MSCT)chest plain and contrast-enhanced scans in judging the nature of pulmonary nodules.The clinical data and MSCT chest plain scan and MSCT enhanced scan images of 125 patients with pulmonary nodules were retrospectively analyzed,and the pulmonary nodule images under MSCT plain scan and MSCT enhanced scan were analyzed.The results showed that the display rate of lobulation sign,pleural stretch sign,vascular bundle sign and vacuole sign under enhanced scan was significantly higher than that of MSCT plain scan(P<0.05).The enhanced CT value and CT value increment of benign nodular lesions[(56.84±11.36)Hu and(25.67±13.65)Hu,respectively]were lower than those of malignant nodular lesions[(79.52±12.32)Hu and(48.95±12.35)Hu,respectively,P<0.05].The diagnostic sensitivity,specificity and accuracy of MSCT plain scan were 65.96%,67.95%and 67.20%,respectively.The diagnostic sensitivity,specificity and accuracy of MSCT enhanced scan were 80.85%,80.77%and 80.80%,MSCT enhanced scan was closer to pathological results.Both plain MSCT scan and MSCT enhanced scan have good clinical value in judging the nature of pulmonary nodules,but MSCT enhanced scan has more prominent diagnostic value for the nature of pulmonary nodules.
