Brain aneurysm: An mri/mra of the brain is an excellent screening test for the detection of even small (2-3 mm) brain aneurysms. Some neurosurgeons may recommend a ct angiogram of the brain or even a cerebral angiogram to be absolutely sure of the initial test results. Discuss the best option for you with a cerebrovascular neurosurgeon.
