Abstract
Nine lesions, 4-ocular (3 melanomas, 1 hemangioma) and 5 orbital (2 perioptic meningiomas, 1 hemangioma, 1 pseudotumor, 1 mucocele), were evaluated by magnetic resonance surface coil imaging at 1.5 T. Small ocular lesions with 3.9-4.5-mm-elevation were demonstrated. The use of 2 different pulse sequences resulted in separation of melanoma from adjacent retinal detachment. Contrast obtained between orbital lesions and the adjacent normal structures was better than that demonstrated with high-resolution computed tomography.
