    Association and Trends in Medicare Denials and Utilization for Brain CT: Indirect Impacts by Targeted Policy Intervention?
    (Current problems in diagnostic radiology, 2022-07-30) French, Robert J; Hirsch, Joshua; Hemingway, Jennifer; Hughes, Danny R; Lerebours, Reginald; Luo, Sheng; Allen, Brian C; Duszak, Richard; Rosman, David A
    Twenty-five years of annual Medicare Physician/Supplier Procedure Summary (PSPS) Master File data were used to assess trends in normalized volume and claim denial rates for brain computerized tomography. Alongside growth in utilization of brain computerized tomography (services, denial rates, fell from 1999-2005 and with relatively leveled growth and less denial rate volatility thereafter. More recent trends in denial rates may be related to policy interventions initially aimed at cost and volume reduction.

    Upper extremity exertional rhabdomyolysis: MR imaging findings in four cases.
    (Radiology case reports, 2020-06) French, Robert J; McCrum, Erin; Horsley, Erin M; Albano, Andrew W; Vinson, Emily N
    While uncommon, exertional-induced rhabdomyolysis is an important diagnostic consideration when encountering hyperintensity within one or more muscles on fluid sensitive sequences in conjunction with signal abnormality in the overlying superficial fascia and subcutaneous fat. The clinical history of recent extreme exercise helps distinguish this disorder from other possible diagnoses, such as cellulitis, necrotizing fasciitis, compartment syndrome, inflammatory processes and diabetic myonecrosis. Patients diagnosed with severe exertional induced rhabdomyolysis often require hospital admission for intravenous hydration and serial laboratory monitoring due to the potential risk of acute renal failure. While contributory, magnetic resonance imaging findings can be nonspecific, and therefore the clinical history is often essential in making this diagnosis.
