Computed tomography in patients with an abdominal mass: effective and efficient? A controlled trial

Abstract

In 28 of 53 patients with a palpable abdominal mass computed tomography (CT) was used as the initial imaging technique, and conventional imaging was used in the remaining 25 patients. The diagnosis was established more quickly in the CT group, and the period of inpatient investigation was shorter. The cost of imaging investigations was higher for the CT group, but this difference was small when compared with the difference in cost of inpatient stay. CT seems accurate in the investigation of a palpable abdominal mass and particularly useful in excluding a pathological cause. The need for the latter is emphasised by the fact that no lesion could be found in 23 of the 53 patients.
