The accuracy of grey-scale ultrasound in the detection and localisation of abdominal and pelvic abscesses was assessed retrospectively in 220 patients in whom an abscess had been suspected at presentation. Thirty-six out of forty abdominal abscesses were correctly diagnosed (90%), while an abscess was correctly excluded in 112 out of 113 patients (99%). Thirty-two out of thirty-three pelvic abscesses were diagnosed (97%), and a pelvic abscess was correctly excluded in 33 out of 34 patients (97%). Thus the overall accuracy of the method was 96.8%, with a sensitivity of 93% and a specificity of 98.6%.
对220例初诊时疑似有脓肿的患者进行回顾性评估，以确定灰阶超声在检测和定位腹部及盆腔脓肿方面的准确性。40例腹部脓肿中有36例被正确诊断（90%），113例患者中有112例被正确排除有脓肿（99%）。33例盆腔脓肿中有32例被诊断出来（97%），34例患者中有33例被正确排除有盆腔脓肿（97%）。因此，该方法的总体准确率为96.8%，敏感性为93%，特异性为98.6%。
