Sirtex SIR-Spheres® Y-90 resin microspheres are a medical device used in Selective Internal Radiation Therapy (SIRT) for liver tumours. SIR-Spheres Y-90 resin microspheres are a permanent implant and for single use only. The biocompatible resin microspheres containing yttrium-90 have a median diameter of 32.5 microns (range between 20 and 60 microns).
Yttrium-90 is a high-energy beta-emitting isotope with no primary gamma emission. The maximum energy of the beta particles is 2.27MeV with a mean of 0.93MeV. The maximum range of emissions in tissue is 11mm with a mean of 2.5mm. The half-life is 64.1 hours. Following administration, 94% of the radiation is delivered in 11 days.
SIR-Spheres microspheres are indicated for the treatment of patients with
advanced inoperable liver cancer.
|Each vial contains 3GBq of yttrium-90 (at the time of calibration) to a total of 5ml water for injection
