磁共振平扫及增强扫描对直肠癌分期诊断的价值分析

Analysis of the Value of Plain and Enhanced Magnetic Resonance Imaging in Staging Diagnosis of Rectal Cancer

目的:分析磁共振平扫及增强扫描对直肠癌分期诊断的价值。方法:回顾性分析2019年1月—2022年2月郑州市第三人民医院接受诊治的66例直肠癌患者的临床资料。所有患者均经病理学诊断确诊,行磁共振平扫及增强扫描,以病理学诊断结果为金标准,分析磁共振平扫、增强扫描以及联合应用对直肠癌分期的诊断效能,评价及应用价值。结果:在直肠癌患者的T分期诊断结果方面,磁共振平扫联合增强扫描在直肠癌T3期诊断的准确率较其他分期患者高,其他分期诊断的特异度、灵敏度和准确度方面相比较,差异有统计学意义(χ^(2)=1.552、1.658、1.947、1.653、0、1.117,P>0.05);在直肠癌患者的N分期诊断结果方面,磁共振平扫联合增强扫描在直肠癌N0期、N1期方面的诊断准确度较磁共振行扫、磁共振增强扫描高,组间比较差异有统计学意义(χ^(2)=3.152、3.246,P<0.05)。结论:临床上对直肠癌患者实施诊断时,应用磁共振平扫及增强扫描,能够准确的进行术前分期,可为临床治疗提供可靠的指导依据,有较高的应用价值。

Objective:To analyze the value of plain and enhanced magnetic resonance imaging in the staging diagnosis of rectal cancer.Methods:66 patients with rectal cancer admitted to the hospital from January 2019 to February 2022 were retrospectively analyzed.They were all confirmed by pathological diagnosis.All patients underwent plain and enhanced magnetic resonance imaging.Based on the pathological diagnosis results as the gold standard,the diagnostic efficacy,evaluation,and application value of plain and enhanced magnetic resonance imaging in the staging of rectal cancer were analyzed.Results:In terms of T-stage diagnostic results in patients with rectal cancer,the accuracy of plain magnetic resonance imaging combined with enhanced scanning in the diagnosis of T3 stage rectal cancer was higher than that of other stages.The specificity,sensitivity,and accuracy of the diagnosis of other stages were compared,with statistically significant difference(χ^(2)=1.552,1.658,1.947,1.653,0,1.117;P>0.05).In terms of N-stage diagnostic results of rectal cancer patients,the diagnostic accuracy of plain MRI combined with enhanced MRI in N0 and N1 stages of rectal cancer was higher than that of conventional MRI and enhanced MRI,with statistically significant difference(χ^(2)=3.152,3.246;P<0.05).Conclusion:In clinical diagnosis of rectal cancer patients,the use of plain and enhanced magnetic resonance imaging can accurately stage the preoperative stage.This provides reliable guidance for clinical treatment,has high application value.
