摘要
目的对直肠癌术前诊断中,MRI常规序列与扩散加权成像(DWI)诊断的价值分析。方法共筛选70例直肠癌患者作为研究对象,均于2021年4月至2023年4月期间于开封市中心医院就诊,术前行单项MRI常规序列扫描、MRI常规序列扫描与DWI序列结合扫描,手术病理结果为金标准,并结合手术结果对比术前影像学TN分期结果。结果MRI+DWI检查T1、T3、T4分期及No、N1、N2a、N2b分期准确度、灵敏度、特异度均高于单项MRI常规序列扫描检查,差异有统计学意义(P<0.05)。结论MRI常规序列及扩散加权成像在术前诊断中具有满意价值,T、N分期符合率、特异度、灵敏度高,能为治疗提供可靠依据。
Objective To analyze the diagnostic value of conventional MRI sequences and diffusion weighted imaging(DWI)in preoperative diagnosis of rectal cancer.Methods A total of 70 patients with rectal cancer were selected as the research subjects,all of whom were treated in our hospital from April 2021 to April 2023.They underwent single conventional MRI sequence scanning,combined scanning of conventional MRI sequence and DWI sequence before surgery,and the surgical pathology results were the gold standard.The preoperative radiological TN staging results were compared with the surgical results.Results The accuracy,sensitivity,and specificity of MRI+DWI examination in T1,T3,T4 staging and No,N1,N2a,N2b staging were all higher than those of single conventional MRI sequence scanning,and the difference was statistically significant(P<0.05).Conclusion Conventional MRI sequences and diffusion weighted imaging have satisfactory value in preoperative diagnosis,with high compliance rate,specificity,and sensitivity in T and N staging,and can provide reliable basis for treatment.
