CHANGES IN RADIOLOGICAL ROUTINES FOLLOWING THE INTRODUCTION OF COMPUTED-TOMOGRAPHY - A RETROSPECTIVE STUDY FROM 2 NORWEGIAN HOSPITALS

Diagnostic imaging routines have changed rapidly during the last two d ecades. The real revolution started with the introduction of computed tomography into routine clinical work in the middle of the 1970s, Simu ltaneously, a tremendous sophistication of ultrasonography took place, and shortly later, magnetic resonance imaging started its ''career.'' The present report explores how the introduction of computed tomograp hy changed imaging routines in two major Norwegian hospitals during th e last 10 to 15 years.
