The accuracy of grey-scale ultrasound in the detection and localization of abdominal and pelvic abscesses was assessed retrospectively in 220 patients in whom an abscess was suspected at presentation. Thirty-six out of 40 abdominal abscesses were correctly diagnosed (90%), while an abscess was correctly excluded in 112 out of 113 patients (99%); 32 out of 33 pelvic abscesses were diagnosed (97%), and a pelvic abscess was correctly excluded in 33 out of 34 patients (97%). The overall accuracy of the method was 96.8%, with a sensitivity of 93% and a specificity of 98.6%.
