Cancer Care and Oncology Services:Interventional and Vascular Radiology techniques can be used in cancer diagnosis and treatment. Biopsies, long term infusion catheters, local tumor ablation, and catheter directed liver tumor therapies can all be performed without surgery. A summary of these cancer support services is available from the American Family Practitioner. Select procedures are described in more detail below.

Small needle biopsies deep in the bodyNeedle biopsy is a medical test performed by Interventional and Vascular Radiologist to identify the cause of an abnormal condition in the body. During the procedure, the doctor inserts a smalll needle, guided by X-ray or other imaging techniques, into the abnormal area. A sample of tissue is removed and given to a pathologist who looks at it under a microscope to determine what the abnormality is -- for example, cancer, a noncancerous tumor, infection, or scar.

IV catheters and Ports for chemotherapyPeople with cancer and other medical conditions sometimes require that tubes be placed into the body so that they can receive medications or nutrients directly into the blood stream, or so blood can be drawn. Once, surgery was required to insert these tubes, but today these procedures can be done without surgery by an Interventional and Vascular Radiologist.
An IV catheter is a tube that is inserted beneath your skin so
There is a simple, pain-free way for doctors or nurses to draw your blood or give you medication or nutrients. When you have a
catheter, you are spared the discomfort of repeated needlesticks.

Radio-frequency ablation--RFARFA is often performed without surgery by Interventional and Vascular Radiologist. In RFA, energy is delivered through a metal tube probe inserted into tumors or other tissues. After the probe is in place, metal prongs open out to extend the reach of the therapy. RF energy generates heat up to 100°C and leads to the death of the cells. More information is available from: Video is also available from: |

Chemo-embolization of liver tumorsA technique called transcatheter chemoembolization is used for some patients with liver cancer or other types of cancer that have spread to the liver. The Interventional and Vascular Radiologist guides catheter through a small nick in the skin at the hip to the artery that feeds the tumor. A combination of chemo- therapy drugs and tiny particles, as small as grains of sand, are then injected directly into the tumor. More information is available from: |

SIR-Sphere treatment of liver tumors Similar to chemo-embolization, Selective Internal Radiation Therapy of liver tumors introduces radioactive particles to liver tumors. This local radiation treats the tumor, while most of the normal liver remains relatively unaffected. More information is available from: |
