Interventional Radiology 

An alternative to traditional surgery for some cancers

Interventional radiology (also known as IR) is the minimally invasive, image-guided treatment of medical conditions that once required open surgery.

By harnessing the power of advanced imaging (ultrasound, X-rays, CAT scans, MRI scans and other innovative methods), interventional radiologists can see inside your body and treat complex conditions including some cancers — less invasively and with unprecedented precision.

What is the advantage of Interventional Radiology?

Interventional radiology procedures can reduce the length of hospital stays, minimize potential complications and save lives. As an alternative to open surgery, interventional radiology procedures may reduce risk, pain and recovery time for your cancer treatment.

The Interventional Radiology Department at Methodist Hospital is a regional referral center specializing in imaging-guided procedures. Interventional radiology procedures are minimally invasive and can often be done in place of surgery, and in some cases, provide treatment for disorders for which there are no surgical alternatives.

Interventional radiology procedures

Today, there are many procedures that once required surgery which can be treated by interventional radiologists. Interventional radiology may provide a treatment option for some of the following:

Kidney cancer
  • Nephrostomy
  • Radio-Frequency Ablation
  • Cryoablation
Liver cancer
  • Biopsies
  • Radio-Frequency Ablation
  • Cryoablation

Y-90 Treatment for Liver Tumors

Where surgery is not possible to remove liver tumors, the Y-90, Yttrium-90 Microspheres (Y-90), treatment may give you an improved quality of life. This minimally invasive procedure uses Selective Internal Radiation Therapy (SIRT) to deliver targeted, micro-particles, called SRI-spheres. This procedure provides internal radiation therapy directly to the tumor.

SIR-Spheres microspheres are microscopic polymer beads that contain the radioactive element yttrium-90 (Y90) and emit beta radiation to kill cancer cells. Due to their small size, they travel easily through the bloodstream directly to the liver. The microspheres become lodged in the small blood vessels supplying the tumor and kill the cancer cells.

SIR-Spheres microspheres and SIRT are considered a safer and more effective method of using radiation to treat liver cancer and are often used in conjunction with chemotherapy.


Interventional Radiologists at Methodist are subspecialty certified in Interventional Radiology by the American Board of Radiology.
