Assessing the Emergence and Evolution of Artificial Intelligence and Machine Learning Research in Neuroradiology

Global results (type 1, 2, and 3). Data characterizing the growth of all AI/ML articles (ie, type 1, 2, and 3). A, The number of all articles published from the first year an AI/ML article was published in the AJNR in 2000 to the article search date on December 3, 2023. *Striped bar in 2023 indicates the extrapolated number of articles published in that year should the search have occurred at the end of the year. B, Pie chart breaking down the share each article type holds among all AI/ML publications. C, Percentile bar graph demonstrating article type share in the last 5 years.

Qualitative type 2 results. General overview of type 2 publication characteristics (n=90). A, A world map showing where studies were conducted. B, Bar graph demonstrating the number of type 2 articles published in years with at least one article published. *Striped bar in 2023 indicates the extrapolated number of articles published in that year should the search have occurred at the end of the year. C, Graphic display of the patient populations and topics studied. VAS = vascular; DEG = degenerative; H/N = head & neck; INF = inflammation.
