A: Radiology refers to the branch of medicine using x-rays, radiopharmaceuticals, magnetic resonance and ultrasound to create images (pictures) of the body that are used to help in the diagnosis and treatment of disease or injury. Interventional radiology is a subspecialty of radiology that uses medical imaging to diagnose and guide the treatment of medical conditions throughout the body percutaneously (via needle-puncture of the skin). Many of the procedures now performed by interventional radiologists have eliminated or reduced the need for surgery.
Not all radiology procedures involve the use of ionizing radiation, such as ultrasound and magnetic resonance. Examinations that do require ionizing radiation are performed at closely monitored levels considered safe. The use of ionizing radiation in children is a special concern and one which our pediatric radiologists have addressed with stringent protocols to minimize dose while maintaining exam quality.
