Aneurysm is a weakness in a blood vessel that enlarges and might bleed into surrounding area. Cerebral aneurysms are the ones found in the brain, most likely in the front part of the brain. If the aneurysm is left untreated, it can grow too large, leading to rupture. Ruptured aneurysm causes blood leakage into the area surrounding it, which might cause death. 70-80 % of those who survive suffer from permanent or temporary disabilities.  Hence, early and accurate diagnosis of aneurysm is highly required. Knowing some parameters about the aneurysm, such as size and location, helps in deciding the right treatment.
