Research Abstract

Research of MRA detection capability of recurrence of coiled cerebral aneurysm using 3 tesla(T) and 1. 5 T MR scanner was performed. Evaluation focused on aneurysm wall contrast enhancement was also performed. Susceptibility artifacts were not so prominent in 3 T MRA in clinical cases. Pre and post gadolinium enhanced MRA revealed aneurysmal residual slow flow, existence of intra-aneurysm thrombosis and aneurysm wall enhancement. Aneurysmal wall enhancement appeared statistically prominently in cases those are necessary to perform another treatment.
