What is Interventional Radiology?

Interventional radiology refers to a variety of minimally invasive therapeutic techniques which rely on image-guidance through the use of fluoroscopy (x-ray video), CT, and ultrasound. Radiographic techniques give the veterinarian visualization of anatomic structures in the respiratory, vascular, gastrointestinal, and urinary tracts. 

​

Examples include placement of stents in the nasopharynx, trachea, urethra, and ureter. CT and fluoroscopy also aid in the placement of guide wires, biopsy needles, and brachytherapy catheters. These procedures replace previously performed open surgical procedures. Minimally invasive procedures result in improved outcomes, faster healing, and reduced pain.
