原发性T2期胃癌增强MSCT影像学表现及与临床病理对照研究

目的探讨原发性T₂期胃癌增强MSCT影像学表现,并与临床病理结果进行分析。方法选取我院2018年7月至2019年6月收治的T₂期胃癌患者71例,收集71例影像学及临床资料,另选择同时期健康体检者45例,比较两组患者胃壁黏膜厚度、MSCT各期扫描CT值,观察胃癌在MSCT检查中图像表现,以临床病理结果为对照,分析MSCT影像诊断分型的符合率。结果T₂期胃癌组CT测量粘膜厚度为(5.79±1.25)mm,明显高于对照组(2.13±0.16)mm,差异有统计学意义(P<0.05);两组患者动脉期、门脉期、平衡期CT值比较存在明显差异,T₂期胃癌组动脉期、门脉期、平衡期CT值显著高于对照组(P<0.05);T₂期胃癌组动脉期至门脉期时,CT值显著上升,静脉期与平衡期CT相比无差异(P>0.05);MSCT对胃癌的术前Type 1-4型诊断正确例数为9例、32例、15例、1例,与临床病理结果对照,其术前大体类型诊断符合为80.28%。结论胃癌增强MSCT可有效显示原发性T₂期影像学表现,对胃癌的术前胃癌大体类型诊断符合率高。

E nhanced MSCT Imaging Finding of Primary T(2) Gastric Cancer and Its Comparison with Clinical Pathological Results

Objective To investigate the enhanced MSCT imaging finding of primary T₂ gastric cancer,and to analyze the comparison with clinical pathological results.Methods 71 patients with gastric cancer at T₂ stage admitted to our hospital from July 2018 to June 2019 were selected.The imaging and clinical data of 71 cases were collected,and 45 healthy subjects were selected at the same time.The gastric mucosal thickness and CT values of MSCT scanning in each phase were compared between the two groups.The image of gastric cancer was observed in MSCT examination.The clinical pathological results were used as the contrast to analyze the accuracy of MSCT in the diagnosis of classification.Results The thickness of the mucosa in the T₂ stage gastric cancer group was(5.79±1.25)mm,which was significantly higher than that in the control group(2.13±0.16)mm.(P<0.05).There were significant differences in the CT values between the two groups in the arterial phase,portal phase,and equilibrium phase.The CT values of T₂ phase gastric cancer group were significantly higher than those of the control group(P<0.05).In the T₂ stage gastric cancer group,the CT value increased significantly from the arterial phase to the portal phase.There was no difference in the the CT value between the venous phase and the equilibrium phase(P>0.05).The number that preoperative 1-4 type of gastric cancer was diagnosed correctly by MSCT was 9 cases,32 cases,15 cases,and 1 case respectively.Compared with clinical pathological results,the accuracy of MSCT in the diagnosis of preoperative general type was 80.28%.Conclusion Enhanced MSCT of gastric cancer can effectively show the primary T₂ imaging findings,and the accuracy in the diagnosis of preoperative general type of gastric cancer is high.
