多层螺旋CT灌注成像在肺癌病理分型中的应用

Application Value of Multilayer Coiling CT Perfusion Imaging in Pathology Classification of Lung Cancer

目的探讨不同病理组织类型肺癌多层螺旋CT灌注成像的特点。方法回顾性分析30例不同病理类型肺癌患者多层螺旋CT灌注成像资料,并加以分析比较。结果腺癌及鳞癌患者PER、PE、TTP及BV值比较,差异均无统计学意义(P>0.05)。随着肺癌分化程度减低,PER、PE和BV值逐渐降低,差异有统计学意义(P<0.05);随着肺癌分化程度减低,TTP值逐渐增高,但差异无统计学意义(P>0.05)。鳞癌Ⅰ型TDC曲线3例,Ⅱ型10例;腺癌Ⅰ型13例,Ⅱ型4例,差异有统计学意义(P<0.05)。结论多层螺旋CT灌注成像能反映不同病理组织类型肺癌的分化程度,可为临床治疗提供重要信息。

Objective To investigate the characteristics of different pathological tissues of lung cancer in multilayer coi -ling CT Perfusion imaging .Methods Multilayer coiling CT perfusion imaging data of 30 cases of lung cancer in different patho-logical types were retrospectively analyzed and compared .Results The PER,PE,TTP and BV rates between adenocarcinoma and squamous carcinoma had no statistically significant difference （P〉0.05）.With the reducing of lung cancer differentiation degree , thePER,PE and BV rates gradually decreased ,the difference was statistically significant （ P〈0.05）;With the reduc-ing of lung cancer differentiation degree,TTP increased gradually,but the difference wasn’t significant（P〉0.05）.There were 3 cases of squamous cell carcinomas with typeⅠTDC curve,and 10 cases with typeⅡTDC curve;and there were 13 cases of adenocarcino-ma with typeⅠTDC curve,4 cases with typeⅡTDC curve,the difference was statistically significant （P〈0.05）.Conclusion Multilayercoiling CT perfusion imaging can reflect the differentiation of different histopathologic types of lung cancer ,and provide important information for clinical treatment .
