Association Between Ownership of Imaging Equipment and Appropriateness of Staging Positron-Emission Tomography in Non-Hodgkin Lymphoma.

ABSTRACT: Physician ownership of imaging equipment has been shown to be associated with greater use of low-value imaging. However, it is unclear whether ownership also influences utilization of appropriate imaging. We conducted a cohort study of older adults diagnosed with three non-Hodgkin lymphomas with distinct guideline recommendations concerning the use of positron emission tomography (PET) during staging (recommended, not recommended, or equivocal). We found patients who were treated by oncologists with PET ownership were more likely to receive a staging PET regardless of lymphoma subtype. However, the difference in utilization by ownership status was smallest (6%, 95% confidence interval = 2% to 11%, P = .01) in the setting of diffuse large B cell lymphoma, where consensus guidelines r
