Fig. 3

Representative transverse in vivo CT images of a rabbit hind leg with VX2 tumors. a Unenhanced (without contrast) CT image acquired 2 weeks after adenovirus injection. Tumors appear as areas of low attenuation (arrows) and are relatively difficult to visualize. b Contrast-enhanced CT image showing well-defined peripheral rim enhancement of each tumor (solid white arrows). Areas of unenhanced necrosis (central low attenuation material) are seen inside the tumor, as indicated by the dotted white arrows
