[Abstract] Objective: To analyze the value of MRI in diagnosis of choroidal melanoma.Materials and Methods: 23 cases of suspected diagnosis of choroidal melanoma were selected. Before operations, MRI examination including plain scan and enhanced scan were performed on all patients. The sensitivity and specificity of MRI were analyzed.Results: Sixteen of the lesions suspected of being choroidal melanomas were found to be hyperintense relative to vitreous on T1WI and hypointense on T2WI. The sensitivity and specificity of MRI was 83.3% and 65.2% respectively.Conclusions: This small retrospective study demonstrates that MRI detects the characteristic signals of choroidal melanoma. MRI is a valuable imaging technique in diagnosis of choroidal melanoma.
