Interventional Radiology Treatments

Our interventional radiologists perform minimally invasive treatments offering reduced risk, quicker recovery and less pain.

Angiography
An injection of a contrast agent into blood vessels to enhance visibility and aid in diagnosis.

Angioplasty and stent placement
Angioplasty is the insertion of an expandable balloon within a vessel to alleviate narrowing. Stenting is the process of placing an expandable cylindrical metal cage to prop open a blood vessel.

TheraSpheres or SIR-Spheres treatment
Also called radioembolization, this therapy is often performed for people who fail TACE or have portal vein thrombosis.

CT guided microwave ablation
Microwave ablation involves placement of a probe from the skin into the center of a liver lesion. Once the probe is placed, microwave energy is used to agitate the water molecules within the lesion, creating a thermal burn and reducing the tumor.

Gastrostomy (feeding tubes)
Using image guidance, physicians can place gastrostomy tubes directly into the stomach for nutritional support.

Needle biopsy
Physicians commonly perform image-guided needle biopsy. Almost any suspicious lesion in the body can be biopsied under image guidance.

Venous access catheters
All varieties of venous access catheters are placed. These include:
  • Dialysis access venous catheters, both temporary and permanent
  • Chest ports for long term IV access, commonly for chemotherapy administration
  • Broviac, Groshong or Hickman catheters, commonly for pulmonary hypertension therapy
  • PICC lines
  • Trifusion catheters, often for plasmapheresis
