How long do radiation seed implants last?

The implants remain in place permanently, and become biologically inert (inactive) after about 10 months.

What are the risks of radioactive implants?

If the intended surgical procedure is near the brachytherapy implant such that: the dose‐rate to the surgical area is high; a surgical intervention may result in dislodging of seeds such that the treatment may be compromised; there is a risk through the course of the surgery of unwarranted radiation exposure to staff; …

How effective is SIRT treatment?

In recent studies, SIRT was most effective in minimizing the risk of tumour progression in the treated lobe and had more of an effect on total liver volume, making it a more suitable modality for selected patients with substantial unilateral disease burden.

How are radioactive seed implants used to treat prostate cancer?

Permanent radioactive seed implants are a form of radiation therapy for prostate cancer. The terms “brachytherapy” or “internal radiation therapy” might also be used to describe this procedure. During the procedure, radioactive (iodine-125 or I-125) seeds are implanted into the prostate gland using ultrasound guidance.

How is radiation safety after a seed implant?

Radiation Safety after Seed Implants Radiation Safety Precautions after a Seed Implant Once the patient’s prostate has been implanted, the seeds are left in place permanently, and the patient actually becomes radioactive.

How are radiation beads inserted in liver tumors?

The beads — about one-third the width of a human hair strand — are inserted by a catheter into the hepatic artery, one of two arteries that supply blood to the liver. The beads become lodged in the tumor, emitting radiation over the course of several weeks.

How is radiation therapy used to treat liver cancer?

Radioembolization As mentioned in Embolization Therapy for Liver Cancer, tumors in the liver can be treated by injecting small radioactive beads into the hepatic artery. The beads then lodge in the liver near the tumor and give off small amounts of radiation that travel only a short distance.
