| Research Abstract |
Strontium-89 bremsstrahlung emission computed tomography (BECT) images of patients were obtained by use of multiple energy windows of a gamma camera. Yttrium -90 BECT images after subtraction of 111In Single photon mission computed tomography images were also obtained by use of the 3 dimensional ordered subsets expectation maximization method, attenuation correction method, and resolution correction. The lower detection limit of 90Y-BECT was approximately 42 kBq/mL.
