What is SIRT radiation?
SIRT generally involves a single delivery of 90yttrium micro-spheres into the hepatic artery. Preferential uptake is achieved into liver tumours, because of their predominant hepatic arterial blood supply. Average tumour doses of radiation in excess of 200 Gy are achieved.
How long does 90yttrium last?
90Yttrium is a high-energy, pure β-emitter with a half-life of 64 hours and maximum tissue penetration of 11 mm, which makes it very suitable for treatment of liver tumours. It is relatively straightforward to use, with few issues relating to radioprotection for the patient, family or attending staff.

Radioembolization is currently used by interventional radiologists to treat primary liver cancer and metastatic cancer to the liver. The most common type of cancer being treated for this is colorectal cancer; however, it may also be used for breast, pancreatic, neuroendocrine tumors, and others.
How should I prepare for the SIRT procedure?
Before the procedure, you may have blood tested to determine how well your kidneys and your blood clotting are functioning. You should inform your doctor of all medications you are taking, including any herbal supplements.
How is SIRT performed?
The SIR-Spheres microspheres treatment is performed as an outpatient procedure by specially trained physicians called interventional radiologists. During the procedure, the radiologist inserts a catheter into the artery in the groin and guides it to the arteries supplying the liver using live X-ray.
How effective is SIRT treatment and are there any side effects?
Clinical studies have shown that SIRT with SIR-Spheres microspheres increases the length of time that the cancer is stable and not growing without adversely affecting the patient's quality of life.
Do patients have to take special precautions and when will I receive the results?
There are some simple precautions that patients need to take during the first 24 hours following the SIRT procedure. These precautions include: thorough hand washing after using the toilet: and cleaning up any spills of body fluids such as blood, urine or stools and disposing of them in the toilet.
