摘要
目的 分析不同病理类型孤立性肺癌患者的多层螺旋CT(MSCT)影像学特征.方法 选取52例孤立性肺癌患者,根据病理类型的不同分为腺癌组(n=34)、鳞状细胞癌组(n=12)和小细胞癌组(n=6).所有患者均进行MSCT检查,比较3组患者的CT值、强化情况、强化方式、相对廓清值及廓清率.结果 MSCT增强扫描30、60s时,腺癌组患者CT值均高于鳞状细胞癌组和小细胞癌组,差异均有统计学意义(P﹤0.05);MSCT增强扫描120 s时,腺癌组和鳞状细胞癌组患者CT值均高于小细胞癌组,差异均有统计学意义(P﹤0.05).腺癌组、鳞状细胞癌组患者的强化净增值均高于小细胞癌组,差异均有统计学意义(P﹤0.05).腺癌组患者均匀强化率高于鳞状细胞癌组和小细胞癌组,差异均有统计学意义(P﹤0.05).MSCT延迟扫描180 s时,小细胞癌组患者相对廓清值、廓清率均高于腺癌组和鳞状细胞癌组,差异均有统计学意义(P﹤0.05);MSCT延迟扫描600 s时,腺癌组患者相对廓清值、廓清率均低于鳞状细胞癌组和小细胞癌组,差异均有统计学意义(P﹤0.05).结论 不同病理类型孤立性肺癌患者的MSCT影像学特征存在明显差异,临床可综合评估不同扫描时间CT值、强化情况等多种影像学特征,为孤立性肺癌患者病理类型的诊断提供参考依据.
Abstract
Objective To analyze the multi-slice spiral CT(MSCT)imaging features in patients with solitary lung cancer of different pathological types.Method Fifty-two patients with solitary lung cancer were selected and divided in-to adenocarcinoma group(n=34),squamous cell carcinoma group(n=12)and small cell carcinoma group(n=6)according to different pathological types.All patients underwent MSCT examination,and the CT value,enhancement condition,en-hancement mode,relative clearance value and clearance rate of the three groups were compared.Result At 30 and 60 s of enhanced MSCT scanning,the CT values in adenocarcinoma group were higher than those in squamous cell carcinoma group and small cell carcinoma group,and the differences were statistically significant(P<0.05).At 120 s of enhanced MSCT scanning,the CT values in adenocarcinoma group and squamous cell carcinoma group were higher than that in small cell carcinoma group,and the differences were statistically significant(P<0.05).The enhanced net increment in ade-nocarcinoma group and squamous cell carcinoma group were higher than that in small cell carcinoma group,and the dif-ferences were statistically significant(P<0.05).The uniform enhanced rate in adenocarcinoma group was higher than those in squamous cell carcinoma group and small cell carcinoma group,and the differences were statistically significant(P<0.05).At 180 s of delayed MSCT scanning,the relative clearance value and clearance rate of small cell carcinoma group were higher than those of adenocarcinoma group and squamous cell carcinoma group,and the differences were sta-tistically significant(P<0.05).At 600 s of delayed MSCT scanning,the relative clearance value and clearance rate of ade-nocarcinoma group were lower than those of squamous cell carcinoma group and small cell carcinoma group,and the dif-ferences were statistically significant(P<0.05).Conclusion There are significant differences in MSCT imaging features of patients with solitary lung cancer of different pathological types.Clinical comprehensive evaluation of CT values at dif-ferent scanning times,enhancement and other imaging features can provide reference for the diagnosis of pathological types of patients with solitary lung cancer.
