Mean (PET/CT)/(PET/MRI) and correlation coefficients for SUVmax, SUVpeak, MTV50%, TLG50%, TLRmax, and TBRmax with Y = X, added as a dotted line. PET, positron emission tomography; SUV, standardized uptake value; MTV, metabolic tumor volume; TLG, total lesion glycolysis; TLRmax, tumor-to-liver ratio; TBRmax, tumor-to-brain ratio.
