2/5 🎉Ramon Barajas Jr MD @OHSURadiology
Dr. Barajas Jr., a neuroradiologist and physician-scientist, develops and clinically translates advanced imaging biomarkers, emphasizing quantitative imaging genomics, neuroinflammation, and molecular radiotheranostics. Congratulations!👏
We’re hiring an Assistant Staff Scientist at @OHSUNews to help build our @OHSUKnight @OHSURadiology neuro-oncology research program.
I’m looking for a collaborator excited about translational science and developing new ideas with our team.

Great to see our review highlighted by @TheAJNR
An overview of the rapidly evolving role of focused ultrasound in neuro-oncology, from blood-brain barrier opening to therapeutic applications and imaging guidance. @PennRadiology
ajnr.org/content/47/6/1463
"This review summarizes the focused ultrasound (FUS) mechanisms and critical role of imaging modalities confirming target engagement, assessing bioeffects and outcomes, and ensuring safety. We explore future directions, including integration of liquid biopsy, AI, and outpatient-ready FUS platforms."

Our recent study showed that T1 subtraction maps can meaningfully impact quantitative assessment of enhancing tumor in pediatric brain tumors. Especially proud of first author @Sina_Bagherii, now a radiology resident at @PennRadiology @TheAJNR

Big congratulations to Dr. Josh Nickerson on being elected Secretary of the American Society of Neuroradiology (ASNR), beginning the leadership path toward President.
He will be the first ASNR President from the Northwest and will help plan the 2029 Annual Meeting.

The energy in Austin was unmatched! 🎸✨ Huge thank you to everyone who joined us for the @The_ASPNR ASPNR promo party—the connections, the conversations, and the community are what make this society so special. Big thanks to the Promo Party sponsors for helping make this event possible:
📷 Guerbet, NordicNeuroLab, and Philips
We’re just getting started. Next stop: sunshine, beaches, and cutting-edge pediatric neuroradiology. ☀️🌴
Get ready to bring that same incredible energy to the coast. See you all at #ASPNR27 in Miami Beach! 🌊🧠
