CT与MRI在直肠间质瘤临床诊断中应用对比分析

Comparative Analysis of CT and MRI in Clinical Diagnosis of Rectal Stromal Tumor

目的:对比CT与磁共振(MRI)诊断直肠间质瘤的应用价值。方法:选取2016年3月至2018年6月在我院就诊的疑似直肠间质瘤患者100例,均行CT、MRI检查,并以病理检查结果为金标准,对比两种诊断方法的结果及诊断价值。结果:经病理组织活检确诊,100例疑似直肠间质瘤患者中60例为直肠间质瘤患者。MRI诊断直肠间质瘤的诊断价值(阴性预测值、阳性预测值、敏感性、特异性及准确性)高于CT诊断,差异有统计学意义(P<0.05)。结论:相较于CT诊断,MRI诊断直肠间质瘤的准确性、敏感性及特异性均较高,有助于提高疾病检出率,为治疗方案的制定提供依据。

Objective:To compare the value of CT and magnetic resonance imaging(MRI)in the diagnosis of rectal stromal tumors.Methods:100 patients with suspected rectal stromal tumors who were treated in our hospital from March 2016 to June 2018 were enrolled.All patients underwent CT and MRI examinations.The results of pathological examination were used as the gold standard.The results and diagnosis of the two diagnostic methods were compared.value.Results:A total of 100 patients with suspected rectal stromal tumors were diagnosed as rectal stromal tumors by pathological biopsy.The diagnostic value(negative predictive value,positive predictive value,sensitivity,specificity and accuracy)of MRI in the diagnosis of rectal stromal tumor was higher than that in CT diagnosis,and the difference was statistically significant(P<0.05).Conclusion:Compared with CT diagnosis,MRI has a high accuracy,sensitivity and specificity in the diagnosis of rectal stromal tumors,which can help to improve the detection rate of diseases and provide a basis for the development of treatment plans.
