MRI is helpful in the diagnosis of insulinoma in the case of failed CT. MRI has better sensitivity than CT scan. Insulinoma shows low intensity on T1 weighted and high intensity on T2 weighted signals, having better visualization on T1 and T2 weighted images with fat suppression. Large tumors (≥ 2 cm) exhibit typically homogenous pattern and ring enhancement. A similar pattern is seen in metastatic lesion as of primary tumor.
