title: Computed tomography: detecting intra-abdominal abscesses.
abstract: Detection of intra-abdominal abscesses by computed tomography (CT) has an estimated accuracy rate of greater than 90 percent. Features helpful in detecting these abscesses include extraluminal gas, the "rind" sign, airfluid interface, and low and high density areas. The author presents three cases to illustrate the usefulness of this modality.
