Future directions in interventional pediatric radiology

In conclusion, the explosion of interventional radiology and its impact on the pediatric patient have resulted in a completely new approach to the subspecialty of interventional pediatric radiology. The interventional radiologist has become an integral part of the management of patients and has become directly involved in the day-to-day care of patients. The use of interventional MR imaging recently has been described in clinical trial. Open-configuration magnets that allow full access to the patient and are equipped with instrument tracking systems provide an interactive environment in which biopsies, endoscopic procedures, and minimally invasive interventions or surgeries are performed. In addition, thermal ablation and image-based control of energy deposition also can be performed. Among these procedures, noninvasive MR-guided focused ultrasound ablation has the most promising future and may replace some conventional surgery. The merging of new and exciting technologies including MR, ultrasound, CT, and fluoroscopy into an environment in which both surgical and interventional radiologic procedures can be performed with image guidance is the basis of the operating room of the future. The role of the interventional radiologist as both the imager and interventionalist is central to this procedural environment; however, the interventional radiologist must accept all the responsibilities of imaging, therapy, patient care, and associated complications.
