State-level variation among radiologists with a majority-neuroradiology practice in terms of being currently subspecialty certified. The intermediate shade corresponds with a percentage within a 60%–70% range, approaching the overall national rate of 65%. Lighter shades correspond with a rate under 60%, and darker shades correspond with a rate of at least 70%.
