title: Detection of abdominal abscesses with gallium-67 citrate: correlative studies with computed tomography.
abstract: Undiagnosed abdominal abscess is a medical problem of substantial clinical importance. The high morbidity and mortality associated with this entity demand prompt, accurate diagnosis. The combined use of gallium scintigraphy and computed tomography provides the imaging tools necessary to accomplish this goal. If the suspected pathology cannot be localized, gallium scintigraphy is the initial diagnostic imaging procedure utilized. When antecedent events or clinical symptoms suggest a specific site for the suspected inflammatory collection, computed tomography (CT) is used to evaluate the area. The strengths and weaknesses of gallium scanning and computed tomography are explored in depth, and particular emphasis is given to proper technique and the avoidance of pitfalls. A logical approach to the use of these modalities in tandem is presented.
