[Comparison of ultrasonic and CT diagnosis of solid liver tumors]

Abstract

A prospective study compares the results of ultrasound and CT diagnostics in 323 patients with liver tumours. The accuracy of both methods is high: the sensitivity of ultrasound comes up to 90.4%, of CT to 96.1%. The important role of the comparatively economic ultrasound in specific tumour diagnosis is eg shown by the fact that if lesions of high and low echogenicity were found in one patient, or if there were found calcifications, the tumour was always a malignoma. This specificity was missing in the cost intensive CT which is also more time consuming and needs i.v. contrast.
