Weighted summation of oxygen-15-water PET data to increase signal-to-noise ratio for activation studies

• Data with the highest possible signal-to-noise (S/N) ratios are desirable when performing nonquantitative perturbation studies with PET and O-15-water. To achieve this, protocols have been suggested in which the stimulus is switched off before the washout
