摘　　要：目的 分析耦合剂充盈法在直肠癌磁共振(MRI)诊断中的应用价值。方法 选择我院2021年1月至2023年2月收治的直肠癌患者75例,术前均给予常规MRI检查及耦合剂充盈后MRI检查,对比两种检查方法 T分期、 N分期及壁外血管侵犯、环周切缘诊断符合情况。结果 耦合剂充盈后MRI的T分期总体符合率显著高于常规MRI (P <0.05),而N分期比较无统计学差异(P>0.05)。耦合剂充盈后MRI壁外血管侵犯诊断符合率显著高于常规MRI (P <0.05)。结论 耦合剂充盈法用于直肠癌MRI检查中可提高术前T分期诊断效果,并可判断患者系膜血管侵犯情况,具有较高的应用价值。Objective To analyze the effect of coupling agent filling in magnetic resonance imaging(MRI)diagnosis of rectal cancer.Methods 75 patients with rectal cancer admitted to our hospital from January 2021 to February 2023 were selected,and given routine MRI or MRI after coupling agent filling before surgery.The T staging,N staging,and diagnostic coincidence of extramural vascular invasion and peripheral incisal edge were compared between the two examination methods.Results The overall coincidence rate of T staging of MRI after coupling agent filling was significantly higher than that of routine MRI(P<0.05),but no statistical difference was found in the N staging(P>0.05).The diagnostic coincidence rate of extramural vascular invasion of MRI after coupling agent filling was significantly higher than that of routine MRI(P<0.05).Conclusions MRI after coupling agent filling for rectal cancer patients can improve the diagnostic effect of preoperative T staging and assess the invasion of mesenteric vessels in patients,with higher application value.
