  1. SUVmax values for patients with low uptake (<5.0) for suspicion of malignancy and the SUVmax data obtained from the PSF and TOF-based algorithms using the two post-filter strategies. The left column shows the lesion volume as measured from the OSEM PET image using a 40% threshold. Values in bold represent lesions that would have changed classification using a strict SUVmax cut-off of 5.0. Values in italics represent increases of greater than 25%.
