AIM
The purpose of the present paper was to review the literature over the last 30 years to assess the value of radionuclide imaging, particularly labeled leukocyte scan, as compared to other imaging modalities in the management of abdominal abscesses.
METHODS
A systematic review of the published studies in humans cited in PubMed written in English, French, German, Italian, and Spanish was made.
RESULTS
Ultrasound (US) has lower sensitivity than leukocyte scan (LS), particularly in patients without localizing signs, while CT has higher sensitivity than US, but less than LS. On the other hand, CT had higher specificity than both LS and US.
DISCUSSION
LS is the more sensitive method to localize abdominal abscesses and may guide dedicated US and CT investigations to improve their diagnostic potential. Further diagnostic evolution is expected from the routine use of hybrid SPECT/CT systems.
目的
本文旨在回顾过去 30 年的文献，评估放射性核素成像（特别是标记白细胞扫描）在腹部脓肿治疗中的价值，与其他成像方式进行比较。
方法
对发表在PubMed 上的英文、法文、德文、意大利文和西班牙文的人类研究进行了系统性综述。
结果
与白细胞扫描（LS）相比，超声（US）的灵敏度较低，尤其是在没有局部定位征象的患者中，而 CT 的灵敏度高于 US，但低于 LS。另一方面，CT 的特异性高于 LS 和 US。
讨论
LS 是定位腹部脓肿更敏感的方法，可指导专门的 US 和 CT 检查以提高其诊断潜能。常规使用 SPECT/CT 混合系统有望进一步提高诊断水平。
