An analysis in Academic Radiology found that aside from declines in patient volume during the pandemic, radiology practices also saw a drop in work relative value units. The study, based on billing information across academic and community hospitals from the first 33 weeks of last year, also found complexity gains in some procedures, including brain and breast imaging, neuroradiology and interventional procedures, possibly because of COVID-19 patients who sought follow-up imaging exams and some patients' "persistent reticence to seek all but the most time-sensitive imaging," researchers wrote.
