The use of low-value imaging: the role of referral practice and access to imaging services in a representative area of Norway

Abstract

Key points MRI is frequently used, and a substantial proportion of MRIs are potential of low value. A small number of referrers account for a large proportion of potential low-value imaging. The use of imaging is not associated with travel distance to imaging facilities or referrers’ experience. Targeting “high-referrers” may be a promising strategy for reducing low-value imaging.
