ABSTRACT

However, randomized aneurysm subarachnoid hemorrhage is associated with an increased risk of death and disability. Clinical and radiological assessment of the risk of ruptured brain aneurysm will help doctors triage patient for treatment and follow-up. However, the mechanism underlying the formation, growth, and rupture of brain aneurysm are unknown. The development of high-resolution magnetic resonance imaging and improvements in post-acquisition treatment protocols have made it possible to examine the aneurysm wall in detail. The 7T and 3T magnetic resonance imaging scanners provide high spatial resolution image with high signal-to-noise ratio. The structure, morphology, location, and development characteristics of the aneurysm wall can be characterized by this level of detail. Wallabnormalities may be related to blood flow, inflammation and wall condition. These tools and measurements provide a unique opportunity to predict the reason of aneurysm development and growth and to identify new sign of intracranial aneurysm instability. Morphological analysis of individual aneurysm, combined with detailed analysis of aneurysm wall and the patient’s medical record, allows for a precise and individualized assessment of the risk of aneurysm rupture.[1]
