Value of Contrast-enhanced CT and Magnetic Resonance Imaging in Localization and Qualitative Diagnosis of Adrenal Tumors
Objective To analyze the value of contrast-enhanced CT and magnetic resonance imaging in localization and qualitative diagnosis of adrenal tumors.Methods The data of 94 patients with adrenal tumors who were admitted to the hospital from January to December 2023 were analyzed retrospectively.All patients underwent contrast-enhanced CT and magnetic resonance imaging.The value of the two methods in localization and qualitative diagnosis of adrenal tumors was compared.Results Histopathological diagnosed 67 cases of benign tumors and 27 cases of malignant tumors.For localization of tumors,88 cases were diagnosed correctly and 6 cases were misdiagnosed by contrast-enhanced CT,with an accuracy rate of 93.62％.For qualitative diagnosis of tumors,57 cases of benign tumors and 23 cases of malignant tumors were diagnosed,and 14 cases were misdiagnosed,with an accuracy rate of 85.11％.For localization of tumors,78 cases were diagnosed correctly and 16 cases were misdiagnosed by magnetic resonance imaging,with an accuracy rate of 82.98％.For qualitative diagnosis of tumors,64 cases of benign tumors and 26 cases of malignant tumors were diagnosed,and 4 cases were misdiagnosed,with an accuracy rate of 95.74％.The accuracy rates of localization and qualitative diagnosis of adrenal tumors using contrast-enhanced CT and magnetic resonance imaging were significantly different(P＜0.05).The AUC values of contrast-enhanced CT for localization and qualitative analysis of adrenal tumors were 0.936 and 0.831.The AUC values of MRI for localization and qualitative diagnosis of adrenal tumors were 0.807 and 0.937.Contrast-enhanced CT was better than magnetic resonance imaging for localization,and inferior to magnetic resonance imaging in for qualitative diagnosis(P＜0.05).Conclusion Contrast-enhanced CT is accurate in locating adrenal tumors,while magnetic resonance imaging is accurate in qualitative diagnosis of adrenal tumors.Combination of the two can be used in clinical diagnosis of adrenal tumors.
