Etay Ziv, MD, PhD - MSK Interventional Radiologist & Early Drug Development Specialist

As an interventional radiologist, I use image guidance (x-rays, ultrasound, CT, PET, or MRI) to perform minimally invasive procedures. The images are used to direct tiny catheters, wires, and needles in order to diagnose and treat tumors. Using image guidance allows us to perform a wide variety of procedures without making large incisions, leading to shorter recovery times and fewer complications. We can also treat tumors by burning or freezing them (ablation) or clogging the arteries that supply them with different materials (embolization). Other procedures we perform include biopsies, opening an obstructed channel (for example, a vessel, a bile duct, or a ureter), or stopping a bleeding vessel.
