Interventional Radiology

We manage all parts of your treatment plan.

Interventional radiology is an integral part of comprehensive patient care, capable of providing less-invasive techniques for the diagnosis and treatment of a broad range of health problems. The interventional radiology team at Austin Cancer Center is a dedicated group of health care professionals who are highly skilled, innovative, and committed to providing the highest quality of patient care for our patients and the community. The most common procedures, listed below, are usually performed on an outpatient basis, often under local anesthesia with intravenous moderate sedation.

Space OAR Hydrogel

Austin Cancer Center is proud to be the most experienced and superiorly equipped team in Central Texas offering the Space OAR Hydrogel for prostate cancer patients. Dr. Gregory Bell has provided dozens of patients with the Space OAR during their prostate cancer treatment. He leads the region with the most advanced imaging technologies that utilize both image guided ultrasounds, coupled with MRI scans to offer precision and accuracy when placing the gel. This procedure is done within the comforts of our office, with minimal sedation or side effects. Space OAR is clinically proven to reduce issues to the surrounding areas of the prostate during radiation by acting as a buffer- providing “space” between the prostate and the rectum. This space allows the radiation oncologists to deliver radiation to only the prostate gland, leaving out the tissues of the rectum. By doing this, the risks of creating issues with the urinary, bowel and sexual systems are greatly decreased.

What is Space OAR?

Space OAR Hydrogel is a simple gel-like solution that expands into form when inserted by the physician. The gel is made up of two elements, including water that produce a synthetic solution. It provides temporary space between organs, and simply dissipates and is excreted by the body in urine after three months to six months, provide protection during radiation treatments.

Who should consider Space OAR?

We strongly suggest Space OAR to nearly all of our patients who will undergo radiation for prostate cancer. However, due to the newness of the product, it is not covered by all insurance companies. We expect more to approve of it in the coming year, but currently Medicare and Aetna are the participating providers. The device can be purchased out of pocket.

Procedures performed by an interventional radiology specialist are becoming increasingly important in the management of patients with cancer. Interventional radiology procedures include imaging-guided biopsies to obtain samples for cytologic or pathologic testing without affecting adjacent structures. Common biopsy sites include lung, liver, lymph node, abdomen, pancreas, prostate, soft tissue, bone (vertebral, marrow with aspiration, deep, and superficial), and thyroid FNA.

PAC Placement and Removal

Portacath placement is a medical procedure to implant a small medical appliance under the skin. The device includes a catheter that connects the port to a vein. Under the skin, the port has a septum through which drugs can be injected and blood samples can be drawn many times, usually with less discomfort for the patient than a more typical “needle stick.”

Once healed, the port should not affect the patient’s daily activities, such as bathing. When the port is no longer needed, it can be surgically removed in another outpatient procedure.

Gold Fiducial Placements

Internal gold fiducials are necessary for tracking the translational and rotational movements of target lesions during stereotactic radiosurgery. The fiducials are generally placed under image guidance in and around the lesions by our interventional radiologist. A fiducial marker is a small gold seed about the size of a grain of rice (0.8mm to 5mm). It is useful in helping focus, or target, the radiation therapy to the area most needed while sparing surrounding tissue.
