Radiologists have at least five to six years of specialized training (residency) after becoming a medical doctor.
An interventional radiologist is a medical doctor who performs minimally invasive, targeted treatments using imaging guidance. Interventional radiologists are board certified radiologists that are fellowship trained in interventional treatments using guided imaging. Their specialized training is certified by the American Board of Medical Specialties.
