Radiology: Interventional Radiology

Interventional radiology (IR) is a 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 radiologic imaging techniques such as X-rays, fluoroscopy, ultrasound, magnetic resonance imaging (MRI), and computed tomography (CT).

IR procedures offer a cost-effective health care alternative to certain conventional medical and surgical treatment. The procedures pose less risk to patients and typically decrease hospitalization time. Frequently, interventional procedures are the only viable therapeutic option for critically ill patients unable to tolerate a surgical procedure.

Special Procedures include:

  • Arteriograms
  • Angiograms
  • Venous Sampling
  • Tube Placements
  • Vascular Access Devices
  • Other Procedures:
    • Biopsy
    • Lymphangiogram
