Background and Aim: Brain stroke is increasingly being recognized in veterinary medicine and difficult to diagnosis. Computed tomography (CT) scan is a tool that can help the diagnosis more easily and rapidly. The objective of this study was to determine the clinical characteristics and quantitated CT images in terms of volume and histogram analysis of the ROIs (rostral cerebral artery, middle cerebral artery, caudal cerebral artery, and caudal cerebellar artery) in dogs with suspected stroke.
Materials and Methods: Six dogs with suspected stroke and 3 healthy dogs were evaluated. General clinical neurological examinations and CT characteristic of the brain were performed on 9 dogs. CT imaging detected regions of brain change in suspected stroke dogs, observed in several regions including frontal, thalamus, and pituitary. We performed quantitative CT including Hounsfield unit (HU), histogram and volume of interest (VOI) of arteries of interested in the brain.
Results: The HU value of the left and right caudal cerebellar artery of suspected stroke dogs were significantly higher than that of control dogs. The histogram of middle cerebral artery of suspected stroke dogs were also significantly higher than that of control dogs. Additionally, the VOI of caudal and cerebellar artery also trend to increase in suspected stroke dogs.
Conclusion: our results demonstrated that CT finding abnormalities in several regions of the brain and in suspected stroke dogs, which helps in formulation of a treatment plan and determining prognosis.
