The use of 99mTc‐HMPAO SPECT brain imaging for a more objective assessment of trauma‐related behavioural changes in a pet dog

Abstract A mixed‐breed dog (2 years) was presented at Ghent University for severe emerging dysfunctional behaviour following a violent fireworks explosion close to the dog. Before this event, the dog displayed no abnormal or dysfunctional behaviour. Behavioural analysis of the dog showed a progression of behavioural problems, which persisted for several months without improvement, despite different treatment efforts. Therefore, a functional brain scan was performed and revealed increased regional cerebral blood flow in the cerebellar area. This finding initiated an exploration into the potential role of functional brain imaging in diagnosing and comprehending complex canine behavioural disorders such as trauma‐related dysfunctional behaviour. This case report aims to underscore the potential application of more objective assessment methods in veterinary behavioural medicine.
