Overview

Magnetic resonance imaging (MRI) is the diagnostic procedure of choice to diagnose a brain abscess.^[1]

MRI

MRI scans appear more sensitive than CT for detecting cerebral edema and early changes correlated to a brain abscess. It can stage the abscess and gauge the response to therapy with more accuracy. Differentiating the central necrosis of brain abscess from other fluid accumulations is more precise with a MRI scan.

T1-weighted images are similar to CT, with a central hypodense signal and surrounding ring-enhancement.
T2-weighted images reveal a central hyperintense area surrounded by a well-defined hypointense capsule with surrounding edema.^[2]
