A CT scan uses X-rays (röntgen beams) and a computer to create a 3D image. The functioning of a CT scan is similar to radiography, where a 2D image is created. In contrast to classic radiography where everything is projected on top of one another, CT scans make perpendicular slides of an organ or area via X-rays. This way, the veterinarian can check how elaborate the tumor is and whether it invades the surrounding tissues. This imaging technique allows a very detailed representation of a certain part of the body and is mainly indicated for bone afflictions. An intravenous contrast fluid can also be administered to the patient to show certain anomalies on the CT scan even more clearly.
