Table 3 Physical indices in JSNM criteria and contrast gain in background of SiPM- and PMT-PET

From: Direct comparison of brain [18F]FDG images acquired by SiPM-based and PMT-based PET/CT: phantom and clinical studies

PET system Contrast (%) CV (%) SD (clinical vs. 30 min) Contrast gain (%)
PMT-PET 58.5 11.1 0.021/0.018 − 1.7
SiPM-PET 72.4 11.5 0.015/0.009 3.5
  1. JSNM criteria: contrast ratio > 55%, CV < 13%, SD < 0.0249
  2. CV Coefficient of variation, JSNM Japanese Society of Nuclear Medicine, PET Positron emission tomography, PMT Photomultiplier tube, SD Standard deviation, SiPM Silicon photomultiplier
