RSNA 2021 Imaging Informatics Preview

Road to RSNA 2021: Imaging Informatics Preview

Our next destination on the Road to RSNA is imaging informatics -- specifically, enterprise imaging, cybersecurity, structured reporting, clinical decision support (CDS), analytics, radiomics, and issues regarding patient access to radiology results. For information on artificial intelligence (AI) topics, you'll want to visit our Artificial Intelligence Preview.

Scientific presentations on imaging informatics at RSNA 2021 will encompass a range of topics, including the effect on radiologist workflow of patient access to imaging results, the effectiveness of using radiological reports and electronic medical record data to predict adverse cardiac events, and the benefits of structured reporting for improving turnaround times. The growing utility of radiomics will also be on display for a variety of clinical indications, including stratifying risk on CT in patients with non-small cell lung cancer and predicting rectal cancer treatment response on MRI.

Although Medicare rules mandating consultation of an approved CDS mechanism to order advanced imaging studies have been delayed -- again -- until January 1, 2023, it's certainly not too early to get up to speed if you haven't already. Scientific presentations this year will discuss, for example, the experience of a pediatric hospital in using CDS for ordering CT exams and the effect of incorporating AI-assisted indications on order appropriateness. You may also want to check out a Monday educational course on best practices to follow when rolling out CDS.

In other RSNA educational opportunities for imaging informatics topics, you can take in a Sunday morning refresher course on cybersecurity for radiology practices, as well as educational courses on the effect of recent legislation on radiology informatics and how to design your imaging platform to be fast, reliable, and ready for disaster recovery. On Monday, a refresher course will also review the imaging informatics clinical "interspace" between radiology and pathology.

What's more, a refresher course on Thursday will delve into the technical issues involved with remote reading and offer strategies for success. In addition, hot topic sessions on Thursday will discuss interactive multimedia reporting and share how imaging informatics tools can be leveraged to engage with patients. An ask-the-expert session will also feature a discussion on how to use informatics tools to measure, display, and monitor performance.

Are you interested in starting or maintaining a point-of-care 3D printing lab? You won't want to miss the RSNA 3D Printing Symposium taking place on Saturday, November 27, from 12:30 p.m. to 5:00 p.m. at McCormick Place. In addition to the Saturday symposium, the RSNA's 3D Printing Special Interest Group is also sponsoring two other sessions: a Sunday educational course on clinical applications for 3D printing and a Wednesday educational course that will enable attendees to have hands-on experience with 3D-printed anatomic models.

See below for our previews of select imaging informatics-related scientific presentations at RSNA 2021. For more information on those talks, as well as other scientific sessions, scientific posters, educational sessions, educational exhibits, refresher courses, and hot topic sessions, view the RSNA 2021 meeting program.
