*[[MRI]] is generally thought to be the imaging modality of choice and can more accurately stage the abscess and gauge the response to therapy.
MRI scans appear more sensitive than CT for detecting cerebral [[edema]] and early changes correlated to brain abscesses. It can more accurately stage the abscess and gauge the response to therapy. It is more accurate in differentiating the central necrosis of brain abscess from other fluid accumulations
:* T1 images are similar to [[CT]], with a central hypodense signal and surrounding ring-enhancement.
* T1-weighted images are similar to [[CT]], with a central hypodense signal and surrounding ring-enhancement.
:* T2 images reveal a central hyperintense area surrounded by a well-defined hypointense capsule with surrounding [[edema]].
