| الوصف: | To assess variability of the average standard uptake value (SUV) computed by varying the number of hottest voxels within an 18F-fluorodeoxyglucose (18F-FDG)-positive lesion. This SUV metric was compared with the maximal SUV (SUVmax: the hottest voxel) and peak SUV (SUVpeak: SUVmax and its 26 neighbouring voxels). Twelve lung cancer patients (20 lesions) were analysed using PET dynamic acquisition involving ten successive 2.5-min frames. In each frame and lesion, average SUV obtained from the N = 5, 10, 15, 20, 25 or 30 hottest voxels (SUVmax–N ), SUVmax and SUVpeak were assessed. The relative standard deviations (SDrs) from ten frames were calculated for each SUV metric and lesion, yielding the mean relative SD from 20 lesions for each SUV metric (SDr N , SDrmax and SDrpeak), and hence relative measurement error and repeatability (MEr–R). For each N, SDr N was significantly lower than SDrmax and SDrpeak. SDr N correlated strongly with N: 6.471 × N -0.103 (r = 0.994; P |
