It’s been almost 50 years since MRI was first used to image a human being, and research into new applications of the modality shows no signs of slowing down. Investigators continue to test MRI’s capabilities, with cardiac imaging joining its “traditional” uses such as tracking the brain’s functional and structural patterns, identifying musculoskeletal conditions, and finding cancer in soft tissues and organs like the brain and spinal cord, the prostate, the breast, and the liver.
Rest assured: This year’s RSNA meeting won’t disappoint when it comes to tracing the arc of MRI innovation. Attendees can expect particular focus on the use of AI with the modality, with presenters reporting on everything from how the combination can better identify conditions such as retropharyngeal edema and help clinicians predict athletes’ time to return to play to how it shows promise for improving the access and affordability of breast cancer screening.
You’ll hear about the benefits of abbreviated breast MRI protocols; the efficacy of low-field imaging (0.55-tesla); the use of the contrast agent gadopiclenol, which appears to allow clinicians to administer a lower gadolinium dose across a variety of studies; and, five years after the COVID pandemic, neuroradiology research on the disease’s long-term effects.
The RSNA will also offer special sessions that tackle “hot topics” relating to the modality, such as remote MRI scanning, the impact of whole body disease screening, and how MRI impacts climate change. Educational gatherings will address topics like the pros and cons of MRI elastography versus ultrasound elastography, techniques to reduce MRI exam time, and emerging breast MRI technologies.
