MRI与CT对鞍区常见肿瘤的诊断效能对比

Comparison on Diagnostic Efficacy of MRI and CT for Common Tumors in the Sellar Region

目的对比MRI与CT对鞍区常见肿瘤的诊断效能。方法回顾性分析本院2017年5月至2019年7月收治的79例鞍区肿瘤患者的临床资料,比较MRI及MSCT检查对鞍区肿瘤的诊断正确率,分析鞍区肿瘤的影像学特征。结果MRI检出垂体腺瘤25例,鞍区生殖细胞瘤12例,颅咽管瘤20例,鞍区脑膜瘤18例,诊断正确率为94.37%;MSCT检查检出垂体腺瘤24例,鞍区生殖细胞瘤7例,颅咽管瘤12例,鞍区脑膜瘤17例,诊断正确率为77.22%,明显高于MSCT检查(P<0.05)。结论MSCT检查及MRI检查可清楚显示鞍区瘤的影像学特点,MRI的总体诊断正确率高于MSCT,但是MSCT显示钙化的能力优于MRI。

Objective To compare the diagnostic efficacy of MRI and CT for common tumors in the sellar region.Methods The clinical data of 79 patients with sellar tumors admitted to our hospital from May 2017 to July 2019 were retrospectively analyzed,the diagnostic accuracy rates of MRI and MSCT for the sellar tumor were compared,and the imaging features of the sellar tumor were analyzed.Results MRI detected 25 cases with pituitary adenoma,12 cases with germ-cell tumor in the sellar region,20 cases with craniopharyngioma,18 cases with meningioma in the sellar region,the correct rate of diagnosis was 94.37%.MSCT examination detected 24 cases with pituitary adenoma,7 cases with germ-cell tumor in the sellar region,12 cases with craniopharyngioma,17 cases with meningioma in the sellar region,with a diagnostic accuracy rate of 77.22%,which was significantly higher than that of MSCT(P<0.05).Conclusion MSCT and MRI can clearly show the imaging features of the sellar tumor.The overall diagnostic accuracy of MRI is higher than that of MSCT,but MSCT shows better calcification than MRI.
