Dual nuclide quantitative imaging with 99mTc/123I using CZT gamma camera

Conclusion: The improved energy resolution offered by CZT leads to no 99mTc contamination into the 123I window. The CZT low energy tail leads to substantial contamination which can be effectively corrected using a calibration phantom. This evidence shows that using a CZT gamma camera allow us to image 123I-MIBG and 99mTc-MDP simultaneously, and lead to reduction of: sedation, CT exposure, scan duration and overall quantity of appointments for children being treated for neuroblastoma.
