Interventional radiology is an exciting, growing and evolving subspecialty of radiology in which both vascular and nonvascular diseases are treated by minimally invasive approaches using small catheters and catheter-based instruments without the need for large surgical incisions or general anesthesia. The procedures are performed with local and intravenous sedation and are guided by radiological imaging techniques such asrays, fluoroscopy, ultrasound and Computed Tomography (CT). The interventional radiologist is trained not only in radiographic imaging but also in percutaneous imageing-guided procedures, and has the clinical skills required to integrate interventional procedures into overall patient management.
