Road to RSNA 2023: AI Preview

Welcome to the first installment of this year’s Road to RSNA preview of the RSNA 2023 meeting. We’re once again providing a modality-by-modality overview of select scientific presentations to serve as your guide to events at McCormick Place.

Our journey along the Road to RSNA begins again with our preview of AI, a topic that has dominated the annual meeting for the past seven years. Research on AI topics will be omnipresent, featuring both in dedicated sessions as well as throughout the scientific program. In fact, it’s hard to find a scientific session without at least one AI-related presentation.

AI’s capability and potential to enhance the practice of radiology will take center stage at RSNA 2023. AI scientific presentations will demonstrate continued progress in areas such as improving and accelerating image reconstruction; triaging critical cases; exploring potential applications for generative AI;  detecting findings initially missed by the radiologist, and, in perhaps one of the potentially more impactful applications for AI, opportunistic screening for risk assessment and incidental disease detection on exams performed for other indications.

Of course, AI also continues to advance in breast imaging, and we’ll provide coverage of key sessions in our upcoming Women’s Imaging section of the Road to RSNA.

See below for previews of AI-related scientific talks we’re highlighting at this year's RSNA meeting. These are just a sample of the content on offer, however; many other scientific presentations, scientific posters, educational courses and exhibits, and plenary sessions on AI topics also await attendees. For more information on those presentations and other abstracts, check out the RSNA 2023 meeting program.

No trip to the RSNA meeting would be complete without visiting the technical exhibits to get up to speed on the latest commercial developments. And you won’t want to miss the AI Showcase, a dedicated exhibition space in the South Hall for AI firms. The AI Showcase is also the home of the AI Theater, which will host the AI Challenge Recognition Event at 4 p.m. Central Standard Time on November 27 as well as daily presentations from vendors.

Interested in a hands-on educational AI experience suitable for beginners? You’ll want to register for classes in the RSNA’s AI Deep Learning Lab. These sessions, which will be held in the Lakeside Learning Center, will cover a wide range of AI topics, such as basics of natural language processing in radiology, data processing and curation for deep learning, and using ChatGPT for DICOM deidentification.

RSNA attendees focused on practical AI matters will likely appreciate the RSNA's Imaging AI in Practice interoperability demonstration, which will demonstrate at the AI Showcase how the technology can be integrated into radiology workflow in real-world clinical scenarios. Meanwhile, visitors can stop by the RSNAI Resource Center at the AI Showcase to get up to speed on the society’s Imaging AI certificate program, the Medical Imaging and Data Resource Center (MIDRC), and other RSNA-led imaging AI education and research activities.
