I am an interventional radiologist — a physician who uses imaging guidance (CT, MR, ultrasound, and fluoroscopy) to do minimally invasive procedures. By using imaging, we can in many cases avoid the need for an operation, thus speeding the patient’s recovery and enhancing quality of life. The types of procedures we perform include venous access, drainages of abscesses, fluid collections and obstructed systems, peripheral angiography, and tumor embolization.
