Tests
Most cerebral aneurysms are not found until they rupture or are detected by brain imaging that may have been obtained for another condition.
The following diagnostic methods are available to provide information about the aneurysm and the best form of treatment:
-
An digital subtraction cerebral angiogram
-
Computed tomography angiogram (CT/CTA)
-
Magnetic resonance imaging (MRI/MRA)
-
Spinal tap for a cerebrospinal fluid analysis may be ordered if a ruptured aneurysm is suspected but is not clearly present on CT.
