a PET maximum intensity projection (MIP) image of patient with right axillary node metastasis at baseline with SULpeak of 1.62 and tumor volume of less than 1.00 cc. Though visually perceptible, Auto-PERCIST™ failed to detect the lesion due to small size. b On the follow-up MIP image, the number of metastatic nodes and the [18F]FDG uptake intensity are increased to SULpeak of 2.84, allowing detection by Auto-PERCIST™
