Comparative accuracy and complementary use of 67Ga-citrate imaging and ultrasound in the diagnosis of abdominal abscesses.

Ultrasound and 67Ga-citrate imaging were used simultaneously for the evaluation of 26 suspected cases of abdominal abscess. Scintiscanning and ultrasonography identified respectively 92% and 69% of the abscesses. Jointly, both modalities detected all 13 abscesses and we suggest an integrated approach in the evaluation of such cases.
