Improved Preoperative Evaluation of Cerebral Cavernomas by High-Field, High-Resolution Susceptibility-Weighted Magnetic Resonance Imaging at 3 Tesla

Abstract

Compared with standard (1.5 T) MRI, 3 T HR-SW-MRI allows superior detection and characterization of cerebral cavernomas. Despite increased susceptibility effects, ie, signal loss at higher magnetic field strengths, the visualization of intralesional tubular structures is feasible. This may be helpful in the diagnosis, presurgical planning, and noninvasive follow-up after gamma-knife radiosurgery.
