摘　　要：探讨电子计算机断层扫描(CT)与磁共振成像(MRI)检查在直肠癌术前分期诊断中的价值。选取河池市第一人民医院2020年1月―2023年11月的60例直肠癌患者作为研究对象,对其实施CT与MRI检查,以病理检查结果为金标准,对比两组患者术前分期诊断情况及准确率。研究结果显示,CT检查中,5例T1期诊断准确,10例T2期诊断准确,28例T3期诊断准确,4例T4期诊断准确;8例N0期诊断准确,21例N1期诊断准确,15例N2期诊断准确。MRI检查中,6例T1期诊断准确,11例T2期诊断准确,31例T3期诊断准确,5例T4期诊断准确;13例N0期诊断准确,25例N1期诊断准确,18例N2期诊断准确。MRI检查的不同T、N分期检查准确率与病理检查无显著差异(P>0.05),CT检查的不同T、N分期检查准确率均显著小于病理检查和MRI检查(P<0.05)。研究发现,相较于CT,MRI检查对直肠癌的术前分期诊断更具价值,且准确率较高,可为患者手术提供必要支持。To explore the value of computed tomography(CT)and magnetic resonance imaging(MRI)in preoperative staging diagnosis of rectal cancer.Sixty patients with rectal cancer from January 2020 to November 2023 at the First People's Hospital of Hechi were selected as the research subjects.CT and MRI examinations were performed on them,and the pathological examination results were used as the gold standard to compare the preoperative staging diagnosis and accuracy of the two groups of patients.The research results showed that in CT examination,5 cases were diagnosed accurately in T1 phase,10 cases were diagnosed accurately in T2 phase,28 cases were diagnosed accurately in T3 phase,and 4 cases were diagnosed accurately in T4 phase;8 cases of N0 stage diagnosis were accurate,21 cases of N1 stage diagnosis were accurate,and 15 cases of N2 stage diagnosis were accurate.In MRI examination,6 cases were diagnosed accurately in T1 stage,11 cases were diagnosed accurately in T2 stage,31 cases were diagnosed accurately in T3 stage,and 5 cases were diagnosed accurately in T4 stage;13 cases of N0 stage diagnosis were accurate,25 cases of N1 stage diagnosis were accurate,and 18 cases of N2 stage diagnosis were accurate.The accuracy of different T and N staging examinations in MRI examination showed no significant difference compared to pathological diagnosis results(P>0.05),while the accuracy of different T and N staging examinations in CT examination was significantly lower than that of pathological examination and MRI examination(P<0.05).Research has found that compared to CT,MRI examination is more valuable and accurate in preoperative staging diagnosis of rectal cancer,and can provide necessary support for patients'surgery.
