There was contrast enhancement of the cavernous structures, most reliably in the bulb and corpus spongiosum and most frequently in entire dogs in the delayed post\u2010contrast phase. In entire dogs, the small testicular vessels most commonly had a vermiform shape in the early post\u2010contrast phase, and a homogeneous appearance in the delayed phase.
