Trends in diagnostic imaging utilization among Medicare and commercially insured adults from 2003 through 2016.
This study examined trends in use of noninvasive diagnostic imaging (NDI) among commercially insured individuals compared to Medicare enrollees from 2003 through 2016. There was more of an increase among Medicare enrollees than commercially insured patients, but both showed upward trends until the early 2010’s where trends began to be flat or decline. The notable exception was for CT imaging among commercially insured patients aged 45-64 years and Medicare enrollees after 2012.

Limited use of surveillance imaging following nephrectomy for renal cell carcinoma.
The researchers evaluated the utilization of follow-up imaging after nephrectomy for renal cell carcinoma (RCC) in nationally representative data. Using Surveillance, Epidemiology, End Results (SEER) data, they found that, in the Medicare population, surveillance imaging is performed in a limited number of patients following nephrectomy for RCC but that increasing tumor stage is predictive of both increased chest and abdominal imaging surveillance.
