Please join us in welcoming our new Department Chair Dr. Hirsch! We are thrilled to have your leadership, experience, and dedication guiding our community forward.

USC has named Joshua A. Hirsch, MD, as the new Chair of the Department of Radiology at the Keck School of Medicine of USC, effective August 17, 2026.

A neurointerventional radiologist who spent his career at Massachusetts General Hospital and Harvard Medical School, Hirsch brings 650+ peer-reviewed publications and a proven record of leading interdisciplinary radiology programs. He has served as president of three major national societies, including the American Society of Neuroradiology (ASNR). His leadership will advance imaging research, clinical excellence, and faculty development at USC.

Welcome to Radiology of USC, Dr. Hirsch. 🩻

The Department of Radiology spans seven clinical divisions with research focused on AI, translational science, and clinical application. Our Nuclear Medicine division is nationally recognized, with hundreds of peer-reviewed publications, tens of thousands of research citations, and more than 300 radiopharmaceutical treatments performed annually.

Our breast imaging program combines multimodality screening and diagnostic tools, including 3D mammography and MRI, across four locations to deliver personalized care by fellowship-trained subspecialists. Our Interventional Radiology division is a nationally recognized leader in advanced, image-guided, minimally invasive care, with expertise in interventional oncology, embolization, portal hypertension, and complex venous disease.

Radiology plays a vital and connective role in our health system. Our department innovates by creating new ways to detect and treat disease and to guide therapy. Questions we ask are aimed at real-world impact and are amplified by translating scientific discovery into clinical application. The work we do has exceptional reach thanks to robust collaboration and our embrace of AI.

A conversation worth tuning into. 🎙️ NRC Commissioner David A. Wright joins Advisory Committee on Medical Uses of Isotopes (ACMUI) Chair Dr. Hossein Jadvar to discuss his path to the NRC, the role of the Advisory Committee on Medical Uses of Isotopes, and his deeply personal experience navigating colon cancer diagnoses.

Did you know MRI machines have absolutely zero radiation? That’s just one of 5 wild facts you probably never knew about this incredible technology.

Watch Dr. Danny Wang break it all down, you’ll never look at an MRI machine the same way again.

Congratulations to Dr. Hossein Jadvar on presenting at the World Federation of Nuclear Medicine & Biology (WFNMB) 2026 Congress in Cartagena, Colombia. Dr. Jadvar shared expertise on Oligometastatic Prostate Cancer: Biology and Trials with international colleagues from every continent. The WFNMB Congress convenes just once every four years, making this a truly prestigious occasion.

New research from Dr. Bino A. Varghese shows why your CT scanner settings matter more than you think

Published in the Journal of Applied Medical Physics, the team found that routine scan settings (radiation dose, scan mode, even gantry tilt) can significantly change the data radiomics extracts from images.

The good news? Some features can be calibrated and corrected, meaning they don't have to throw out valuable data from different scanners.

Why it matters: Accounting for imaging variability helps ensure radiomics reflects true biology, not scanner artifacts, critical for multicenter studies and clinical translation.

Imaging is a critical part of modern medicine, informing care across injury, infection, cancer, chronic disease and more. But today’s gold standard techniques—ultrasound, X-ray, computed tomography (CT) and magnetic resonance imaging (MRI), each have their limitations.

In a proof-of-concept study funded by the National Institutes of Health, Dr. Charles Liu, professor of clinical neurological surgery, urology and surgery at the Keck School of Medicine of USC, director of the USC Neurorestoration Center, and his team and the California Institute of Technology (Caltech) have shown that an innovative, noninvasive technique can be used to quickly collect 3D images of the human body, from head to foot. The technology combines ultrasound and photoacoustic imaging, which detects sound waves generated by light, to simultaneously collect images of both tissue and blood vessels. The findings, just published in the journal Nature Biomedical Engineering, have the potential to address current gaps in medical imaging.
