Figure 1From: Impact of 18F-FDG PET/CT on target volume delineation in recurrent or residual gynaecologic carcinomaComparison of mean tumor volumes using the different manual and SBR delineation techniques. Error bars indicate standard deviation (SD) on the mean. Results are shown for the gross tumor volume (GTV) delineated on CT (GTVCT1 and GTVCT2) and PET/CT-based GTVs obtained by manual delineation of contours (GTVPET/CT1 and GTVPET/CT2), and signal-to-background ratio (SBR)-based adaptive thresholding (GTVSBR).Back to article page
