Early 67Ga scintigraphy for the localization of abnominal abscesses

Sixty patients suspected of having abdominal abscesses were evaluated by early and delayed 67Ga scintigraphy. The 67Ga scintigraphs obtained 6 hr after injection correctly localized 18 of 20 abdominal or retroperitoneal abscesses. An additional 13 patients with abnormal scintigraphs had clinically established infections. In no instance was an abscess or inflammatory focus present on delayed scintigraphs that was no evident on the 6-hr study. Two false-positive and two false-negative studies were recorded. Early 67Ga scintigraphy is warranted in patients with suspected abdominal abscesses.
