原始语种摘要: Abstract(#br)Purpose(#br)This study aimed to determine whether the SiPM-PET/CT, Discovery MI (DMI) performs better than the PMT-PET/CT system, Discovery 710 (D710).(#br)Methods(#br)The physical performance of both systems was evaluated using NEMA NU 2 standards. Contrast (%), uniformity and image noise (%) are criteria proposed by the Japanese Society of Nuclear Medicine (JSNM) for phantom tests and were determined in images acquired from Hoffman and uniform phantoms using the DMI and D710. Brain and whole-body [ 18 F]FDG images were also acquired from a healthy male using the DMI and D710.(#br)Results(#br)The spatial resolution at 1.0cm off-center in the DMI and D710 was 3.91 and 4.52mm, respectively. The sensitivity of the DMI and D710 was 12.62 and...
