To obtain the sequential true transverse image of a cranial cruciate ligament the computed tomography gantry was angled such that the scanning plane was parallel to the fibula. True transverse images of cranial cruciate ligaments were identified on every sequential image beginning just proximal to the origin of the cranial cruciate ligament distal to the tibial attachment after the administration of iodinated contrast medium. A significant decrease in the area of the cranial cruciate ligament was identified on CTA imaging after partial surgical rupture of the cranial cruciate ligament. This finding implies that CTA can be used for assessing partial cranial cruciate ligament ruptures in dogs. Keywords arthrography computed tomography cruciate ligament dog rupture Introduction Most ligament injuries in canine stifle joints involve some kind of cranial cruciate ligament rupture including partial rupture 9 . This results in severe instability and predisposes the joint to degenerative changes 7 . The cranial cruciate ligament is attached to a fossa on the caudal aspect of .
