摘要
目的:探究在结直肠癌手术之前T分期、N分期中,多层螺旋CT(multi-slice spiral CT,MSCT)成像技术、磁共振成像(MRI)的应用作用与意义。方法:选取海丰县彭湃纪念医院2021年1月—2022年3月收治的60例可手术切除结直肠癌病例,将其平均随机分为两组,对照组于术前进行MSCT检查,试验组术前进行MRI检查和MSCT检查,根据结直肠癌的TNM分期标准,对比对照组和试验组对结直肠癌的T、N分期诊断正确率,研究总结MSCT成像技术联合MRI检查对结直肠癌患者术前T、N分期的诊断价值。结果:经过术后病理检查明确T分期,试验组30例患者中5例T1~T2期,13例T3期,12例T4期;对照组30例患者中6例T1~T2期,12例T3期,12例T4期。对照术后病理检查结果,试验组诊断正确率为86.67%(26/30),对照组诊断正确率为63.33%(19/30),两组诊断正确率对比差异有统计学意义(P <0.05)。经过术后病理检查明确N分期,试验组30例患者中3例N0期,12例N1期,15例N2期;对照组30例患者中4例N0期,11例N1期,15例N2期。对照术后病理检查结果,试验组诊断正确率为96.67%(29/30),对照组诊断正确率为66.67%(20/30),两组诊断正确率对比差异有统计学意义(P <0.05)。结论:在结直肠癌患者术前T、N分期诊断中,相比于单用MSCT,MRI检查和MSCT检查联合应用的价值更为显著,可以提高诊断正确率,为临床诊断提供支持,同时也为手术方案的制定提供参考。
Objective To explore the application and significance of multi-slice spiral CT(MSCT)imaging technology and magnetic resonance imaging(MRI)in T stage and N stage before colorectal cancer surgery.Methods A total of 60 patients with surgically resectable colorectal cancer admitted to Pengpai Memorial Hospital in Haifeng County from January 2021 to March 2022 were randomly divided into 2 groups.The control group underwent preoperative MSCT examination,and the experimental group underwent preoperative MRI and MSCT examination.According to the TNM staging criteria of colorectal cancer,the diagnostic accuracy of T and N staging of colorectal cancer was compared between the control group and the experimental group,and the diagnostic value of MSCT imaging technology combined with MRI examination for preoperative T and N staging of colorectal cancer patients was summarized.Results T stage was determined by postoperative pathological examination.Among the 30 patients in the experimental group,5 cases were stage T1-T2,13 cases were stage T3,and 12 cases were stage T4.In the control group of 30 patients,6 patients had stage T1-T2,12 patients had stage T3,and 12 patients had stage T4.The diagnostic accuracy of the experimental group was 86.67%(26/30),and that of the control group was 63.33%(19/30).The difference between the two groups was statistically significant(P<0.05).N stage was determined by postoperative pathological examination.Among the 30 patients in the experimental group,3 cases were stage N0,12 cases were stage N1 and 15 cases were stage N2.In the control group,there were 4 N0 stage patients,11 N1 stage patients,and 15 N2 stage patients.The diagnostic accuracy of the experimental group was 96.67%(29/30),and that of the control group was 66.67%(20/30).The difference between the two groups was statistically significant(P<0.05).Conclusion In the preoperative T and N staging diagnosis of colorectal cancer patients,compared with MSCT alone,the combined application of MRI and MSCT has more significant value,which can improve the diagnostic accuracy,provide support for clinical diagnosis and provide reference for the formulation of surgical plan.
