From: Impact of external cooling with icepacks on 68Ga-PSMA uptake in salivary glands

Radiotracer activity in unilateral (left-sided) icepack group (N = 24) Absolute difference (%) p value*
Left parotid gland   Right parotid gland

 SUVpeak (mean, ± SD) 9.93 (± 3.32) UVpeak (mean, ± SD) 11.25 (± 3.25) 1.32 (11.73) 0.00
 SUVmean (mean, ± SD) 4.36 (± 1.75) SUVmean (mean, ± SD) 4.78 (± 1.43) 0.42% (8.79) 0.14
Left submandibular gland   Right submandibular gland    
 SUVmax (mean, ± SD) 12.83 (± 3.23) SUVmax (mean, ± SD) 13.21 (± 3.46) 0.38 (2.88) 0.15
 SUVpeak (mean, ± SD) 10.85 (± 2.90) SUVpeak (mean, ± SD) 11.12 (± 2.90) 0.27 (2.43) 0.19
