Fig. 1From: Differentiation of soft tissue and bone sarcomas from benign lesions utilizing 18F-FDG PET/CT-derived parametersPET images depicting manually drawn VOI in three planes and the method used to calculate HF. (a) Axial plane. (b) Sagittal plane. (c) Coronal plane. (d, e, f) MTV decreasing gradually with increasing threshold (40, 50, 60% of SUVmax, respectively). (g) The slope of the threshold-volume function curve was calculated analogously to HFBack to article page
