Dynamic computed tomography to measure tissue perfusion in spontaneous canine tumors.

Dynamic computed tomography (CT) is widely used in humans to determine tumor perfusion via time-attenuation curves. Five types of time-attenuation curves have been identified and shown to have prognostic relevance in humans. The goal of our study was to assess the feasibility of this technology in spontaneous canine tumors and to determine time-attenuation curves and perfusion patterns in different tumor types.
