Physician Self-Referral of Lumbar Spine MRI With Comparative Analysis of Negative Study Rates as a Marker of Utilization Appropriateness
American Journal of Roentgenology, 05/24/2012
Paxton BE et al. – Lumbar spine MRI examinations referred by the financial–interest group were significantly more likely to be negative than those referred by the no–financial–interest group. Lesion frequency among positive scans suggests similar severity of disease between the two patient populations. Patients imaged by the financial–interest group were significantly younger than those imaged by the no–financial–interest group.
