MRI

MRI is generally thought to be the imaging modality of choice and can more accurately stage the abscess and gauge the response to therapy.

T1 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.
