MRI
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-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]
