@RSNA The @RSNA needs our support to continue advancing imaging science and elevating the next generation of radiology leaders!

[Carolyn Meltzer, MD @CMeltzerMD]

Best way to start the year.

[Keck School of Medicine of USC @KECKSchool_USC]

Dean's POV 📸 So much fun enjoying ice cream and açai bowls with students at the Welcome Social last week. Great conversations, great energy, and an even better sign of things to come this year.

The path to solving Alzheimer's disease is paved with data🧠💻
In a new video, our director, Arthur Toga, explains how our researchers use advanced neuroimaging and AI to uncover the brain changes behind Alzheimer's, and how our Image and Data Archive, the world's most widely used repository of observational Alzheimer's data, powers global research and drug development.

@KECKSchool_USC @uscnorris such important work for the health of all

[RSNA @RSNA]

The RSNA #RandEFoundation has approved more than $4.5 million in grants for 2026, funding 79 new projects designed to advance medical imaging, radiation oncology and radiology education.

From improving early cancer detection and personalized treatment to developing AI-powered training tools for future radiologists, this year's awardees are tackling some of healthcare's most pressing challenges.

One step closer to CAR-T for solid tumors....

[Keck School of Medicine of USC @KECKSchool_USC]

Solid tumors have dodged CAR-T cell therapy for a decade, no clear target for immune cells to find. @uscbme engineers built SHIFTERS: focused ultrasound that makes tumor cells briefly display a marker CAR-T cells already know. #CancerResearch. https://t.co/Aqc6IoOXea

@KECKSchool_USC @USCLONI fascinating work!

New Keck School research: @uscloni researchers found PM2.5 and NO2 exposure linked to divergent cortical thickness patterns in Alzheimer's-vulnerable regions: thinner in older women, thicker in younger men. Published in NeuroToxicology #AlzheimersResearch https://t.co/LC34kTJftn

Such an exciting time- welcome new students ✌️✌️✌️

[Keck School of Medicine of USC @KECKSchool_USC]

Welcome to the Trojan Family. It's going to be an incredible year. ✌️

[Keck School of Medicine of USC @KECKSchool_USC]

Congrats to our 2025-2026 Dean's Master's Scholars and Dr. Rodolfo Montes Scholars at the Keck School of Medicine of USC, 11 students spanning neuroimaging, addiction science, public health, and more. https://t.co/RlryBAD55e

Research shows that 3D MR elastography (MRE) provides more precise liver stiffness measurements than conventional 2D MRE in adults with severe obesity, with potential benefits for fibrosis staging and monitoring treatment response. Read more: https://t.co/gESKJapSe8

What’s beyond the white coat? For Dr. Lily Dara, it’s painting, dogs, fantasy novels and a passion for discovery.

As a hepatologist with the USC Digestive Health Institute, part of Keck Medicine of USC, she cares for patients with rare and complex liver diseases while conducting research aimed at advancing treatments and improving outcomes.
Her approach to medicine is deeply personal, guided by a commitment to treating every patient with the same care she would want for her own family.

Get to know Dr. Dara, the experiences that shaped her and what inspires her work in and outside of medicine: https://t.co/pagIfVt4j8

A new large national study led by the Keck School of Medicine of USC finds differences in multiple sclerosis death rates by age, race, sex and geography. The study also found that co-occurring conditions, such as high blood pressure and cardiac arrest, are linked to increased mortality among people with MS. Read here: https://t.co/Ny3Ox1uFpF

Dean's POV 📸 Putting community first.

During orientation, our incoming students spent a day serving LA. Events included volunteering at @HomeboyInd, the largest gang rehabilitation and re-entry program in the world. This is how we build measurable health improvements, together.
