To evaluate whether there is an association between academic productivity and NIH grant funding in the interventional radiology community. A database containing board-certified US interventional radiologists and their region, institution, academic rank, and gender was previously created for a study evaluating H-index in 2021. The Scopus database was used to add the H-index values for 2023. The NIH RePORTER system was queried to collect any NIH grant funding received by each interventional radiologist. Among the 832 interventional radiologists, 37 physicians received NIH grant funding, 33 being male (85%) and 4 being female (11%). Male interventional radiology (IR) physicians received a median NIH funding of 1, 427, 636 (SD=21, 124, 820) while female IR physicians received a median NIH funding of 1, 822, 019 (SD=1, 663, 298). IR professors received a median of 3, 334, 302 (SD=31, 818, 268), associate professors a median of 2, 050, 739 (SD=1, 159, 055), assistant professors a median of 956, 402 (SD=2, 065, 859), and unranked physicians a median of 565, 961 (SD=389, 468. 9) in NIH grant funding. There were no significant differences between NIH grant funding found between genders (p=0. 9) or academic ranks (p >0. 43). However, bivariate analysis did show that H-index was positively and significantly correlated with NIH grant funding (coefficient= 592, 753, p< 0. 001). The H-index has a significant positive correlation with NIH grant funding. Although 85% of all funding was granted to men, there is no significant difference between awards with regards to gender as well as amongst academic ranks. However, the small number of interventional radiologists receiving NIH grant funding limits our understanding of NIH grant funding in IR.
