Effectiveness of computed tomography in the diagnosis of intra-abdominal abscess: A review of 111 patients.
Computed tomography detected intra-abdominal abscess with 97% accuracy in 111 patients who underwent 135 separate scans. A true negative ratio of 0.98, and a true positive ratio of 0.96 was obtained. Further important findings, unrelated to the presence of abscesses, were detected in 41 of the 135 scans. The information given by computed tomography significantly modified clinical management in over 55% of studies performed.
