MRI

  • MRI is an emerging imaging modality for the diagnosis of suspected intra-abdominal abscesses.
  • Abdominal abscesses demonstrate decreased signal intensity on T1-weighted images and homogeneous or heterogeneous increased signal intensity on T2-weighted images; abscesses are observed best on gadolinium-enhanced, T1-weighted, fat-suppressed images as well-defined fluid collections with rim enhancement.
  • Limited availability and high cost, as well as the need for MRI-compatible patient support equipment and the length of the examination, currently limit its usefulness as a diagnostic tool in acute peritoneal infections, particularly for patients who are critically ill.
  • Necessary if receiving peritoneal dialysis and a diagnosis of peritonitis is uncertain after a physical exam and an examination of the dialysis fluid.
