Dalla Palma, C. Ricci, S. Magnaldi (INVITED)] In order to maximise the benefits of modern diagnostic procedures and to minimise costs both for the health service and the individual, criteria for selecting patients undergoing diagnostic procedures must be carefully established. This review analyses the main factors (related both to patients and technology) which should influence our diagnostic choices. The general meaning of efficacy, efficiency, cost and benefits in a radiological milieu is defined and then applied to a number of highly practical situations where new technologies (ultrasonography, computed tomography and magnetic resonance) have revolutionised diagnostic approaches in the past decade. The review emphasises that referral criteria must be founded on a 'first priority' basis so that decisions as to diagnostic protocol are taken on the basis of clinical features, epidemiological data and simple laboratory tests; the consequent steps in diagnostic protocols are influenced by a priori knowledge of efficacy, efficiency, prognostic and therapeutic value of the diagnosis and cost considerations.
