Abstract：Objective: To explore the differential diagnosis value of dynamic enhanced MRI and CT for adrenal tumors.Methods: A total of 49 patients with adrenal tumor admitted to our hospital from October 2013 to September 2018 were selected. Pathological examination results showed that 45 patients had adrenal adenoma (18 cases of aldosterone adenoma, 17 cases of cortisol adenoma, 10 cases of non-functional adenoma), and 4 cases of metastatic tumor. Pathological examination results were taken as the "gold standard" to compare the diagnostic accuracy of the two examination methods, and to compare the location and qualitative diagnosis of adrenal tumor patients with MRI and CT examination. Results: The diagnostic accuracy of enhanced MRI plain scan was 83.67%, and that of CT plain scan was 57.14%. The diagnostic accuracy of MRI was significantly higher than that of CT, with statistically significant difference (χ2=10.825, P<0.05). Among the 49 patients diagnosed by surgery, 31 were benign adrenal tumors and 18 were malignant adrenal tumors. The location detection of adrenal tumors indicated that the detection accuracy of CT was significantly higher than that of MRI, with statistically significant differences (P<0.05). The qualitative detection of adrenal tumor showed that the accuracy of MRI was significantly higher than that of CT, and the difference was statistically significant (P<0.05). Among benign tumors, the sharpness of MRI images was better than that of CT, and there was no statistically significant difference between the two inspection methods in malignant tumors (P<0.05). Conclusion: For diagnosis of adrenal tumors, CT and MRI both have advantages and deficiencies. CT determines more accurately the tumor location, and MRI helps more accurately identify tumor to be benign or malignant. The option should be made according to the actual circumstance of patients.
