From: Same same but different: dopamine transporter SPECT on scanners with CZT vs. NaI detectors
FP-CIT SPECT images of a 65-year-old male first acquired on a NaI (right) and directly afterward on a CZT (left) system. The subject was visually rated as a neurodegenerative PS. For the CZT data, z-scores calculated with the CZT NDB corresponded with the visual assessment, whereas the utilization of the GE NDB resulted in discordance. Semiquantitative results of the NaI system were in line with the visual rating
