    Abstract:

    BACKGROUND AND PURPOSE: Imaging self-referral is increasingly cited as a contributor to diagnostic imaging overuse. The purpose of this study was to determine whether ownership of MR imaging equipment by ordering physicians influences the frequency of negative cervical spine MR imaging findings. MATERIALS AND METHODS: A retrospective review was performed of 500 consecutive cervical spine MRIs ordered by 2 separate referring-physician groups serving the same geographic community. The first group owned the scanners used and received technical fees for their use, while the second group did not. Final reports were reviewed, and for each group, the percentage of negative study findings and the frequency of abnormalities were calculated. The number of concomitant shoulder MRIs was recorded. RESULTS: Five hundred MRIs meeting inclusion criteria were reviewed (250 with Financial Interest, 250 with no Financial Interest). Three hundred fifty-two had negative findings (190 with Financial Interest, 162 with no Financial Interest); there were 17.3% more scans with negative findings in the Financial Interest group ( P = .006). Among scans with positive findings, there was no significant difference in the mean number of lesions per scan, controlled for age (1.90 with Financial Interest, 2.19 with no Financial Interest; P = .23). Patients in the Financial Interest group were more likely to undergo concomitant shoulder MR imaging (24 with Financial Interest, 11 with no Financial Interest; P = .02). CONCLUSIONS: Cervical spine MRIs referred by physicians with a Financial Interest in the imaging equipment used were significantly more likely to have negative findings. There was otherwise a highly similar distribution and severity of disease between the 2 patient samples. Patients in the Financial Interest group were more likely to undergo concomitant shoulder MR imaging.

  • Journal Club: Shoulder MRI utilization: relationship of physician MRI equipment ownership to negative study frequency.
    American Journal of Roentgenology, 2013
    Co-Authors: Timothy J. Amrhein, Ben E. Paxton, Matthew P. Lungren, James D. Eastwood, Ramesh C. Srinivasan, Sin-ho Jung, Ramsey K. Kilani
    Abstract:

    OBJECTIVE. The purpose of this article is to determine whether ownership of MRI equipment by ordering physicians influences the frequency of negative shoulder MRI scans. MATERIALS AND METHODS. A retrospective review was performed of 1140 consecutive shoulder MRI scans ordered by two separate referring physician groups serving the same geographic community. The first group (Financially incentivized) owned the scanners used and received technical fees for their use. The second group (non–Financially incentivized) did not own the scanners used and had no direct Financial Interest. All examinations were performed with identical protocols and were interpreted by a single radiologist group without Financial Interest in the imaging equipment used. The frequency of negative examinations and the number of abnormalities in each positive study was tabulated for each group. RESULTS. A total of 1140 shoulder MRI scans met inclusion criteria; 255 were negative (142 for the Financially incentivized group and 113 for the...

  • Physician self-referral of lumbar spine MRI with comparative analysis of negative study rates as a marker of utilization appropriateness.
    American Journal of Roentgenology, 2012
    Co-Authors: Ben E. Paxton, Matthew P. Lungren, James D. Eastwood, Ramesh C. Srinivasan, Sin-ho Jung, Ramsey K. Kilani
    Abstract:

    OBJECTIVE. Financial Interest in imaging equipment may affect the imaging referral patterns of ordering physicians. The purpose of this article is to determine whether ownership of MRI equipment by ordering physicians predicts the likelihood and prevalence of positive findings on lumbar spine MRI as a metric for comparison of utilization. MATERIALS AND METHODS. A retrospective review was performed of 500 consecutive diagnostic lumbar spine MRI examinations in one radiology practice ordered by two separate referring physician groups serving the same geographic community: one with Financial Interest in the MRI equipment used (Financial-Interest group) and one without Financial Interest in the MRI equipment used (no-Financial-Interest group). Negative examinations and total number of lesions per positive study were recorded for each group. RESULTS. Five hundred scans met inclusion criteria during the study period (250 in the Financial-Interest group and 250 in the no-Financial-Interest group). The negative s...
