What is Pediatric Interventional Radiology?

At St. Jude, our Interventional Radiology (IR) team uses advanced imaging — like ultrasound, fluoroscopy, CT and MRI — to perform minimally invasive procedures on children of all ages. These techniques often take the place of traditional surgery, which means:

  • Smaller incisions (or sometimes no incision)
  • Lower risk of complications
  • Shorter recovery times
  • Less pain and discomfort for the patient

Expert care designed for children

Our pediatric IR program offers a wide range of diagnostic and therapeutic procedures, with a special focus on caring for children with cancer. Our team provides cutting edge cancer treatments, minimally invasive pain procedures, and a variety of other supportive care techniques to ensure the best possible outcomes.

A Team You Can Trust

The patient will be treated by a pediatric interventional radiologist and nurse practitioners who partner with our patient’s primary care team. This close collaboration means care that is personalized, seamless, and designed around our patient’s unique needs. Our IR clinicians are supported by:

  • ARRT-VI registered radiologic technologists
  • Specially trained registered nurses
  • Child life specialists who help reduce fear and anxiety

With a shared commitment to gentle, effective care, everything we do is centered on providing high-quality, minimally invasive treatments in a child-friendly environment—so our patients feel safe, supported, and cared for every step of the way.
