SUV of tumor and surrounding tissuse.
On the left side of the figure, two lines are drawn along axial (blue) and radial (red) directions of the lesions. The SUV under the two lines are sampled and shown on the right. SUV15%, SUV30%, SUV40%, SUV2.5 baselines are shown along the Y axis. SUV of lesion and normal tissues reveals many overlapping regions.

Solid rendering of manually contoured reference (green) and RG result (red).
The first row shows the result of 18F-FDG; the second row shows the result of 11C-Choline. The DSCs of the two modalities were 67.06% and 74.11%, respectively. (11C-Choline scans were obtained 3 d after 18F-FDG).
