Automatic calculation of MTV and TLG by PET VCAR application of Advanced workstation 4.4 (GE Medical Systems, Milwaukee, WI). Whole-body ¹⁸F-FDG PET MIP image; the transaxial, coronal image, and the ¹⁸F-FDG PET/CT fusion transaxial image of patient with left breast cancer and left axillary lymph node metastasis is shown. Inside the green cuboid VOI covering breast cancer lesion, another VOI is automatically delineated on FDG avid portion (SUV threshold > 2.0). And MTV, TLG of the VOI are automatically calculated
