Optimal energy window selection of a CZT-based small-animal SPECT for quantitative accuracy

Our results demonstrated that the proper energy window should be carefully chosen based on quantitative measurements in order to take advantage of desirable characteristics of CZT-based small-animal SPECT. These results provided valuable reference information for the establishment of new protocol for CZT-based small-animal study, and may offer insights into the potential of multiple-isotope imaging with CZT-based small-animal SPECT.
