SUV and FF values calculated from 18 participants; Tscv and EE values calculated from 20 participants. SUV, calculated from PET, was integrated in 80 minutes; FF, calculated from MR imaging, at end of the scan was integrated at 80 minutes; Tscv from IRT analysis was integrated in 120 minutes in supraclavicular region; and average EE was integrated in 120 minutes. Analysis adjusted with body weight (kilograms).
EE, energy expenditure; FF, fat fraction; IRT, infrared thermography; MR, magnetic resonance; PET, positron emission tomography; SUV, standardized uptake value; Tscv, anterior supraclavicular temperature.
