The RSNA meeting always showcases the particular benefits MRI brings to the healthcare enterprise, and this year will be no exception. One of the modality's exciting growing edges is cardiac imaging, and attendees can expect to hear a broad range of research on the topic, from how real-time MRI can be combined with deep learning to assess cardiac volumetry and how it can help clinicians "map" the effects of stroke, to using 7-tesla MRI to evaluate ventricular structure and function in patients with high blood pressure and identifying myocarditis after COVID-19 vaccination.
Along with cardiac imaging, other MRI themes at the RSNA will include the use of AI with the modality (for example, the combination appears to reduce breast MRI contrast dose); implementing faster protocols for quicker scans and lower healthcare costs; and exploring whether low-field MRI (that, is, 0.55-tesla) is as clinically useful as conventional 1-tesla and 3-tesla systems for applications ranging from point-of-care MRI for critically ill patients to lumbar spine visualization. Another big theme for MRI at the meeting will be its use in women's imaging: look for research on how DWI-MRI in particular shows promise as an additional breast cancer screening tool and as a way to predict women's response to cervical cancer treatment.
MRI is a workhorse when it comes to neuroradiology, and attendees will get the scoop on how the modality can reveal the effects of type 2 diabetes on the brain; characterize the progression of Alzheimer's and Parkinson's disease; screen and triage patients with suspected cerebrospinal fluid (CSF) disorders; and help diagnose amyotrophic lateral sclerosis (or ALS -- formerly known as Lou Gehrig's disease).

MRI illuminates gray-matter changes in diabetic patients
Sunday, November 26 | 1:00 p.m.-1:10 p.m. | S4-SSNR01-1| Room E351

Fetal MRI can detect genetic syndromes
Sunday, November 26 | 3:10 p.m.-3:20 p.m. | S5-SSOB01 | Room N229
In this session, fetal MRI’s role in detecting genetic syndromes will be explored, including how atypical temporal lobe asymmetry could be a soft marker for an underlying genetic condition.
Men with diabetes carry more brain plaque load than women
Tuesday, November 28 | 10:10 a.m.-10:20 a.m. | T3-SSNR07-5 | Room S405

How does low-field MRI compare to standard for lumbar spine imaging?
Tuesday, November 28 | 5:20 p.m.-5:30 p.m. | T8-SSNR09-5 | Room N227B
Low-field MRI produces comparable diagnostic quality images for lumbar spine imaging compared with a standard MRI field strength, according to study results to be presented Tuesday afternoon.
AI can enable lower breast MRI contrast dose
Wednesday, November 29 | 9:40 a.m.-9:50 a.m. | W3-SSBR08-2 | Room S406A
