Value of gallium-67 citrate scanning in Crohn's disease: concise communication

Abstract

A frequent problem in Crohn's disease is the distinction between exacerbated inflammation of the bowel, which can be treated medically, and intra-abdominal abscess, a common complication that requires surgical management. We present evidence that the gallium scan is of value in making this distinction. From a series of 11 studies, negative gallium scans correctly excluded abscess in over half. All patients were symptomatic at the time of the scan. Most patients with active Crohn's disease do not have abnormal gallium uptake and in these patients the gallium scan is useful to exclude the possibility of abscess.
