文摘

The performance of a pre-clinical SPECT/CT system for 188Re imaging is investigated. Image quality and image quantification is assessed for two multi-pinhole collimators. Monte-Carlo simulations of the pre-clinical SPECT system were performed. Image quality and image quantification of 188Re was comparable to 99mTc performance. 188Re images suffered from higher noise due to large number of down-scatter photons.
