Computed tomography (CT), ultrasound, and 111In-labeled leukocyte scans are all used in the evaluation of abdominal abscesses. In this study, 170 patients in whom one, two, or all three of these modalities were used retrospectively reviewed. Diagnostic accuracy of 96% for CT, 90% for ultrasound, and 92% for 111In leukocyte scans was achieved. It was often necessary to use more than one modality to arrive at a correct diagnosis. The advantages and disadvantages as well as the causes for false positive or false negative interpretations of each of these modalities are reviewed. Analysis of the different examinations resulted in a suggested sequence by which patients can be examined, based upon their clinical condition. Patients who are not critically ill and/or who have no localizing signs should be studied first with 111In-labeled leukocyte scans. If, however, localizing signs should or the patient's condition necessitates prompt intervention, CT or ultrasound should be the first study performed.
计算机断层扫描（CT）、超声和铟-111标记白细胞扫描均用于腹部脓肿的评估。在本研究中，对170例使用了上述一种、两种或全部三种检查方法的患者进行了回顾性分析。CT的诊断准确率为96%，超声为90%，铟-111白细胞扫描为92%。通常需要使用不止一种检查方法才能得出正确诊断。本文回顾了这些检查方法各自的优缺点以及假阳性或假阴性结果的原因。对不同检查的分析得出了一个建议的检查顺序，可根据患者的临床情况进行检查。病情不危急和/或无定位体征的患者应首先进行铟-111标记白细胞扫描。然而，如果有定位体征或患者的病情需要立即干预，则应首先进行CT或超声检查。
