Magnetic resonance imaging (MRI) is the cornerstone of neurological diagnosis in the veterinary clinical setting. As a mainstay, clinical MRI involves the use of standard structural sequences. These sequences provide vital information on structural and intensity brain changes that occur secondary to neurological disease which help to refine differential diagnoses and direct clinical decision making. There is, however, a limitation to the amount of information that can be deduced from these standard sequences, with definitive diagnoses rarely possible and several disease processes, such as epilepsy and degenerative myelopathy, that they are insensitive at detecting. These limitations are well recognised in the wider field of neuroimaging research and have resulted in the development of multiple advanced neuroimaging techniques that are more sensitive to neuropathology and provide more information towards the functional abnormalities present. Once such technique is diffusion tensor imaging (DTI).
