Interventional Radiology

Cedars-Sinai interventional radiologists, Marc L. Friedman, MD, and H. Gabriel Lipshutz, MD

Two of our interventional radiologists, Marc L. Friedman, MD, and H. Gabriel Lipshutz, MD

Our interventional radiologists are board-certified physicians who specialize in minimally invasive, image-guided treatments. Interventional radiologists pioneered these minimally invasive techniques to treat many conditions that once required traditional surgery and are now treated with typically less risk, less pain and a shorter recovery time than open surgery. 

During these procedures, our physicians along with their expert team of nurses and technologists use X-rays, CT, ultrasound and advanced imaging techniques to direct a thin tube or catheter to a specific location in the body to diagnose or treat disease. The accuracy of this targeting often allows the treatment to be done with less damage to the surrounding healthy tissue than traditional surgical methods.
