Overview
High-resolution contrast enhanced MRI is the diagnostic technique of choice and the most sensitive technique for evaluating retinoblastoma.
MRI
High-resolution contrast enhanced MRI is the diagnostic technique of choice and should be used whenever possible to answer the key clinical questions. It has been proved to be the most sensitive technique for evaluating retinoblastoma[1] especially regarding tumor infiltration of the optic nerve, extraocular extension and intracranial disease. The 3D-multiplanar capability provide detailed examination of tumors and retrobulbar and intracranial structures. The tumor appears as heterogenously enhancing soft tissue mass with various degrees of calcification.[2] Lesions are typically hyperintense to vitreous on T1-weighted sequences and hypointense to vitreous on T2-weighted sequences.[3]
