摘要 目的:比较动态增强 CT、MRI 对肾上腺肿瘤的鉴别价值。方法选择经术后病理证实为肾上腺肿瘤患者62例,所有患者均行平扫及动态增强 CT、MRI 检查,对比两种检查方法对肾上腺肿瘤定性及定位诊断准确率,对比两种检查方法下肾上腺腺瘤与非腺瘤的肿瘤廓清率。结果增强 CT 定位、定性检查正确率为别为96.77%、90.57%,分别略高于增强 MRI 的91.94%、86.79%,但两者差异均无统计学意义(χ2=0.479、0.376,均 P >0.05);与 MRI 检查相比较,53个肾上腺腺瘤与9个非腺瘤的绝对廓清率及相对廓清率在增强 CT 延时5 min 时差异均有统计学意义(t =2.962、2.018,均 P <0.05),53例肾上腺腺瘤与9例非腺瘤的矫正廓清率在增强 MRI 延时5 min 分别为(33.41±20.17)%、(14.74±12.16)%,差异有统计学意义(t =2.684,P <0.05)。结论动态增强 CT、MRI 对肾上腺肿瘤的鉴别诊断水平较高,两种检查方法对其定位与定性诊断正确率均较高,是可靠的诊断肾上腺肿瘤手段。 Objective To compare the clinical value of dynamic enhanced CT,MRI in differential diagnosis of adrenal tumors.Methods 62 patients with adrenal tumor by pathologically confirmed in our hospital were select-ed.All patients underwent unenhanced and dynamic enhanced CT,MRI examination.The qualitative and adrenal tumor localization diagnostic accuracy,the adrenal adenomas and non adenoma tumor clearance rate of the two meth-ods were compared.Results The accuracy of enhanced CT positioning,qualitative examination were 96.77%, 90.57%,respectively,which were slightly higher than those of the MRI enhancement(91.94%,86.79%),but the differences were not statistically significant (χ2 =0.479,0.376,all P 〉0.05).53 adrenal adenomas and 9 cases non-adenomas absolute and relative clearance rate clearance rate in enhanced CT 5 min delay time,the differences were statistically significant (t =2.962,2.018,all P 〈0.05).53 cases adrenal adenomas and 9 cases non adenoma clear-ance of correction in the enhanced MRI delay 5min,respectively (33.41 ±20.17)%,(14.74 ±12.16)%,the differ-ence was statistically significant (t =2.684,P 〈0.05).Conclusion Dynamic enhanced CT,MRI are good methods for differential diagnosis of adrenal tumors,two methods have location and qualitative diagnosis correct rate.So dynamic enhanced CT,MRI are reliable means of diagnosis of adrenal tumors.
