Comparative of dynamic enhanced CT,MRI differential diagnosis of adrenal tumors / 中国基层医药

ABSTRACT

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.
