Posted on March 31, 2008

Australian company SIRTeX has received FDA approval to begin trials of their injectable, beta radiating microspheres thought to directly target intrahepatic tumor sites. From the product brochure:SIR-Spheres microspheres consist of biocompatible microspheres containing yttrium-90 with a size between 20 and 60 microns in diameter. Yttrium-90 is a high-energy pure betaemitting 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. In the...
