Interobserver variability of the three methods. Perfusion quantifications were performed by three experienced nuclear physicians with planar, manual, and automated segmentation in ten patients. The data are expressed as average relative standard deviation (%) of the relative distribution in each lobe/lung. The gray error bars indicate the standard deviation of the ten patients
