Fig. 3From: Biodistribution and radiation dosimetry of the novel hypoxia PET probe [18F]DiFA and comparison with [18F]FMISOMIP images of [18F]DiFA in a healthy volunteer. Decay-corrected anterior maximum-intensity projections of PET at 1, 2, 4, and 6 h (from left to right) after an injection of 718.7 MBq of [18F]DiFA in a 74.0-kg male volunteer. There was a rapid clearance of activity in the kidneys, liver, and bladder. Gallbladder activity peaked following the first meal after the PET acquisition at 4 h, then decreased with timeBack to article page
