What is Interventional Radiology? Pediatric interventional radiology (IR) is a medical field that specializes in minimally invasive diagnostic or therapeutic procedures using imaging guidance, in children. IR doctors guide small needles, catheters and other small medical equipment into the body through tiny incisions in the skin. These instruments are manipulated within in the body by the radiology doctors, who guide the instruments by seeing into the body, using X-ray, CT scan, ultrasound or MRI.
