Children’s National Hospital Interventional Radiology (IR) performs a full range of minimally invasive, image-guided procedures to both diagnose and treat disease in infants, children and adolescents. Specially trained pediatric interventional radiologists perform minimally invasive interventions using imaging tools to guide the procedures. 

The best available quality of care is made possible by this dedicated team of interventional radiologists, advanced practice providers, radiologic technicians, registered nurses, surgical coordinators and anesthesiologists. We also are at the forefront of research in minimally invasive diagnostics and therapy through the Sheikh Zayed Institute for Pediatric Surgical Innovation, where we are working on enhancing local drug delivery techniques in cancer and thrombosis as well as evaluating the role of magnetic resonance (MR)- guided high intensity focused ultrasound to treat pediatric soft tissue and bone tumors.

Interventional Radiology describes a field of specialized surgery where doctors use state-of-the-art technology, such as ultrasound, X-Ray, CT, and MRI to visualize the inside of the human body. When they have a clear image of the target inside the body, experts can guide instruments, such as catheters, to the target area for diagnosis or treatment.

IR in children has reduced the need for open surgery in many conditions, providing minimally invasive alternatives. Our facilities were created to provide specialized care for children. We have a specialized IR suite and an operating room with state-of-the-art imaging equipment.

Preparing for your Procedure

We welcome you and your child to Interventional Radiology. Please read the specific information on your child’s procedure and bring questions with you on the day of the procedure. If there are any concerns prior to your procedure, we can be reached at 202-476-3791.  

It is very important that you arrive promptly for the procedure. Generally, we ask you to register nearly one to two hours before your procedure time and arriving late may cause further delays for your child.

If your child is not feeling well or is not in their usual state of health, please call us. It is very important that we know before the procedure. You can call us at 202-476-3791.

The Interventional Radiology team at Children’s National looks forward to seeing you and your child.
