  1. During the image quality readings, each image was assigned a “1” (for optimal image quality) or a “0” (for non-optimal image quality). The numerator of the image quality score is the sum of both readers’ scores, and the denominator is the total number of PET/CT and PET scans that were read and scored
  2. Data are presented as n/N (%)
  3. CT computed tomography, PET positron emission tomography
