磁共振成像与螺旋CT在结直肠癌诊断及术前分期中的应用价值对比

Comparison of the application value of magnetic resonance imaging and spiral CT in the diagnosis and preoperative staging of colorectal cancer

目的:探究磁共振成像(MRI)与螺旋CT在结直肠癌诊断及术前分期中的应用价值。方法:选取2021年1月-2022年2月巨野县人民医院收治的经临床病理检查明确为结直肠癌的患者100例,所有患者均行MRI、螺旋CT及病理检查。以病理分期检查结果为金标准,分析MRI、螺旋CT在结直肠癌中的诊断价值。结果:经病理组织活检明确T1期6例,T2期40例,T3期50例,T4期4例;N0期48例,N1期38例,N2期14例;MRI检查T2、T3期灵敏度及准确率均高于螺旋CT检查,差异有统计学意义(P <0.05);MRI检查N0期、N1期灵敏度及准确率均高于螺旋CT检查,差异有统计学意义(P <0.05);Kappa检验显示:MRI检查T分期与病理结果的一致性均良好;螺旋CT检查T1、T2分期与病理结果的一致性尚可;螺旋CT检查T3、T4分期与病理结果的一致性良好;MRI检查N0期、N1期与病理结果的一致性均尚可;MRI检查N2期与病理结果的一致性良好;螺旋CT检查N0期、N2期与病理结果的一致性尚可;MRI检查N1期与病理结果的一致性不佳。结论:MRI与螺旋CT均可鉴别诊断结直肠癌,但MRI诊断效能更高,可更加准确地鉴别TN分期,值得临床推广。

Objective To explore the application value of magnetic resonance imaging(MRI) and spiral CT in the diagnosis and preoperative staging of colorectal cancer. Methods 100 patients with colorectal cancer admitted to Juye County People’s Hospital from January 2021 to February 2022 were selected and confirmed by clinical and pathological examinations, all patients underwent MRI,spiral CT and pathological examinations. The diagnostic value of MRI and spiral CT in colorectal cancer was analyzed based on the results of pathological staging. Results 6 cases of T1, 40 cases of T2, 50 cases of T3 and 4 cases of T4 were confirmed by pathological biopsy;48 cases in stage N0, 38 cases in stage N1 and 14 cases in stage N2;The sensitivity and accuracy of MRI in T2 and T3 were higher than those of spiral CT, the difference is statistically significant(P < 0.05);The sensitivity and accuracy of MRI in phase N0 and N1 were higher than those of spiral CT, the difference is statistically significant(P < 0.05);Kappa test showed that T staging of MRI was consistent with pathological results;The T1 and T2 staging of spiral CT was consistent with the pathological results;The T3 and T4 staging of spiral CT was consistent with the pathological results;The consistency of MRI examination in stages N0 and N1 with pathological results was fair;The N2 phase of MRI was consistent with the pathological results;The consistency of spiral CT examination in N0 and N2 stages with pathological results was acceptable;The consistency between MRI examination of N1 stage and pathological results is poor. Conclusion MRI and spiral CT can differentiate colorectal cancer, but MRI has higher diagnostic efficacy and can more accurately differentiate TN staging, which is worthy of clinical promotion.
