The purpose of this study is to establish and validate a methodology for estimating the standard deviation of voxels with large activity concentrations within a PET image using replicate imaging that is immediately available for use in the clinic. To do this, ensembles of voxels in the averaged replicate images were compared to the corresponding ensembles(More)

Respiratory alkalosis, produced by mechanical ventilation, has been identified as a cause of hypoxemia, which improves when PaCO2 is normalized or increased. Moreover, moderate hypercapnia has been suggested for the treatment of acute respiratory failure (ARF) by the results observed in experimental animals. To correct the situation of hyperventilation one(More)
