PET images overlaid on CT images. For delineation of VOIS with obvious and high PET-uptake, the color (Sokoloff) scale was set so that the peak level of the structure was presented as white, whereupon the delineations were done at the yellow border of the uptake. VOIager 4.0.7 (GE Healthcare, Uppsala, Sweden) was used for delineation of healthy organs/tissues. Hermes Hybrid Viewer (Hermes Medical Solutions AB, Stockholm, Sweden) ) was used for delineation of aorta and adrenals.

5 consec. Slices PET/CT

The VOIs were delineated in Aorta-Descendens, in 5 consecutive slices, covering 4 central pixels

Anatomical landmark: first slice was located five image slices below the level where the bronchi enter the lung. Delineated in five consecutive slices downwards.
