Background The purpose of this study is to examine the presence of gender disparity represented by industry payments and research funding within the field of interventional neuroradiology. Methods Payment information was collected using the Centers for Medicare and Medicaid Services Open Payment database for the year 2019. Kruskal-Wallis tests were used to analyze differences in annual compensation based on sex in $US, while controlling for geographic factors, academic rank, and h-index. A sample t-test was performed to look at gender differences in h-indexes. Results The study cohort was comprised of 893 interventional neuroradiologists, 73 (8.2%) of which were female. Of the $48889.20 in mean annual payments reported in the database, $5847.13 (11.2%) went to female interventional neuroradiologists (P<0.05). The significant difference in compensation between male and female neuroradiologists was evident after controlling for state-level variance and academic position. There was a statistically significant difference in total reimbursement (P<0.001), research (P<0.001), consulting (P<0.04), food and beverage (P<0.02), and compensation for services other than consulting between males and females (P<0.02). A statistically significant difference was found for h-index based on gender (males=16.7, females=10.1; P<0.001). Conclusions Our findings indicate that in the field of interventional neuroradiology, females receive less research funding and private industry compensation, have lower h-indexes, and are less likely to occupy the highest academic positions. The difference in funding did not differ when accounting for geographic state of practice and academic rank. Future studies should work to identify potential contributory factors of these trends.
