多模态MR成像技术在直肠癌T分期中的应用价值

Application value of multimodal MR imaging in T staging of rectal cancer

目的探讨多模态MR成像技术在直肠癌T分期中的应用价值,旨在指导临床选择合理的治疗方案,以提高对该疾病的治疗效果。方法选择我院收治的68例直肠癌患者为研究对象,所有患者均给予常规MR平扫、扩散加权成像(DWI)、MR增强扫描技术显示直肠癌病变,并对直肠癌病变进行T分期,将其诊断结果和手术病理结果进行对比。结果MR+DWI+MR增强多模态扫描对直肠癌T分期的诊断准确率为83.8%,明显高于常规MR平扫的70.6%(P<0.05)。结论多模态MR成像技术能多方面充分显示肿瘤侵及肠壁的深度及与周围组织侵犯范围,提高直肠癌分期的诊断准确率,为临床治疗方案提供参考依据。

Objective To investigate the application value of multimodal MR imaging in T staging of rectal cancer, in order to guide clinical selection of reasonable treatment scheme and improve the treatment effect of this disease.Methods Sixty-eight patients with rectal cancer admitted in our hospital were selected as the study objects.All patients underwent conventional MR scan, MR diffusionweighted imaging (DWI) and MR enhanced scanning technology to display the lesions of rectal cancer.T-staging was performed for the lesions of rectal cancer, and the diagnostic results were compared with the surgical pathological results.Results The diagnostic accuracy of T staging of rectal cancer by MR+DWI+MR enhanced multimodal scanning was 83.8%, which was significantly higher than 70.6% by conventional MR scanning (P<0.05).Conclusion Multimodal MR imaging can fully display the depth of invasion of intestinal wall by tumors and the range of invasion with surrounding tissues in many aspects, improve the diagnostic accuracy of rectal cancer staging, and provide reference for clinical treatment programs.
