Institutional Survey of Neuroradiology Scholarship in the US: A Bibliometric Study

While the origins of neuroradiology scholarship can be traced back to individual pioneers, the current status of institutional level neuroradiology scholarship has not been explored. We aimed to examine present day academic institutional contributions to the neuroradiological literature in the United States.

Neuroradiology fellowship programs in the US were identified, and a Scopus search for numbers of papers published, citations, and h-index for each institutions' neuroradiology faculty between July 2025 and August 2025 was conducted. Median h-index, mean h-index and median paper numbers by institution were recorded.

We identified 94 neuroradiology fellowship programs with 1282 faculty producing 63,769 manuscripts and 2.4 million citations, with Mayo Clinic Rochester (MCR) over-represented in both publications and citations. Rankings varied depending on metric: while MCR, University of California San Francisco, Massachusetts General Hospital, and Washington University consistently ranked highest overall, smaller programs such as University of California Davis and Thomas Jefferson University rose in h-index due to highly prolific individual faculty. There were discrepancies between published commercial diagnostic radiology program rankings and neuroradiology-specific scholarly output.

Several institutions across the nation make disproportionate contributions to neuroradiology scholarship. While scholarship can influence program reputation, program rankings do not necessarily parallel neuroradiology academic productivity.
