摘　　要：目的分析应用多层螺旋CT灌注成像对胃癌手术前评估的临床价值。方法回顾性分析本院2017年2月至2019年8月收治的70例胃癌患者的临床资料,分析不同肿瘤分化程度、远处转移、肿瘤生长部位及TNM分期中胃癌MSCT灌注参数值情况。结果胃癌中晚期的MTT、BV值与早期比较差异无统计学意义(P>0.05),BF、PS值比较差异具有统计学意义(P<0.05);低分化组的MTT、BV值高于高分化组,BF、PS值低于高分化组;淋巴结转移组的BF、MTT、BV、PS值均高于无淋巴结转移组;远处转移组BF、MTT、BV值与无远处转移组比较无差异(P>0.05),PS值比较有差异(P<0.05)。不同生长部位之间的BF、BV、MTT、PS值比较无差异(P>0.05)。结论MSCT检查可显示胃癌的影像学特点,CT灌注成像能反映胃癌的血流动力学变化,在胃癌术前评估中具有重要价值。Objective To analyze the clinical value of multi-slice spiral CT perfusion imaging in preoperative evaluation of gastric cancer.Methods The clinical data of 70 patients with gastric cancer who were admitted to our hospital from February 2017 to August 2019 were retrospectively analyzed,the MSCT perfusion parameters of gastric cancer with different degrees of tumor differentiation,distant metastasis,growth site of tumor and TNM staging were analyzed.Results There was no significant difference in the MTT and BV values in the middle and late stages of gastric cancer compared with the early stage(P>0.05),the difference in BF and PS values was statistically significant(P<0.05);the MTT and BV values of the poorly differentiated group were higher than those of the highly differentiated group,and the BF,MTT,BV and PS values in the lymph node metastasis group were higher than those in the no lymph node metastasis group,there were no significant differences in the BF,MTT,and BV values between the distant metastasis group and the no-distant metastasis group(P>0.05),the difference in PS values was statistically significant(P<0.05).There were no significant differences in BF,BV,MTT and PS between different growth sites(P>0.05).Conclusion MSCT examination can clearly show the imaging features of gastric cancer,CT perfusion imaging can reflect the hemodynamic changes of gastric cancer,and has important clinical value for preoperative evaluation of gastric cancer.
