Selected PET radiomic features remain the same.

ABSTRACT:

Purpose

We investigated whether PET radiomic features are affected by differences in the scanner, scan protocol, and lesion location using ¹⁸F-FDG PET/CT and PET/MR scans.

Results

SUV, TMR, skewness, kurtosis, entropy, and homogeneity strongly correlated between PET/CT and PET/MR images. SUVs were significantly higher on PET/MR_{0-2 min} and PET/MR_{0-10 min} than on PET/CT in gynecological cancer (p = 0.008 and 0.008, respectively), whereas no significant difference was observed between PET/CT, PET/MR_{0-2 min}, and PET/MR_{0-10 min} images in oral cavity/oropharyngeal cancer. TMRs on PET/CT, PET/MR_{0-2 min}, and PET/MR_{0-10 min} increased in this order in gynecological cancer and oral cavity/oropharyngeal
