study the role of different imaging modalities in the detection and characterization of Adrenal lesions. Materials and Methods: In the present study for a period of 1 year comprised of 45 patients. All patients with Adrenal masses were evaluated with ultrasonography, NECT, CECT and few were further evaluated by MRI Confirmation of diagnosis was by histopathology, clinical course or by pre and post operative confirmation of imaging findings wherever possible. Results: Of 45 cases 22 were benign, 16 were malignant and 07 were infectious. The distribution of Benign and malignant lesions were 48.8 : 35.5. In our study most of the Adrenal lesions are mixed echogenic constituting 15 (33.3%), which include both benign and malignant lesions. Most of the mixed echogenic lesions are malignant. Necrosis was commonly noted in most of the lesions constituting 12 (26.6%) of cases which is seen in Benign and Malignant and also in small & large lesions. Plain CT was done in 40 cases out of which 18 (40%) shoed mixed attenuation. Among them most were Malignant lesions. Calcifications are easily detected and are in Infectious and Malignant lesions constituting 10 (44%) of cases. CECT was done in 39 cases out of which most of them showed Non-Homogenous enhancement 19 (42.2%). In our study MRI was done only in 7 cases out of it 3 were Adenoma, which show more than 40% signal drop in T1 out of phase images which is diagnostic of Adenoma and differentiate it from Adenoma. Most of the lesions in our study were Metastasis mostly from Carcinoma Lung. Second common lesion in our study was Adrenal Adenoma. Ultra sound was done in all cases among which it could detect 34 (75 %) Lesions were detected. Plain CT was done in 40 cases among which 34 (185%) and CECT was done in 39 cases and diagnostic accuracy of CECT was 100%. Conclusion: This study detected the role of imaging modulaties in the detection and characterisation of adrenal lesions. It analysed imaging features of various adrenal lesions.
