As veterinary practice advances globally, the outcome of most treatments depends largely upon appropriate definitive diagnosis. Over the years projection radiography was the main imaging technique being utilised for radio-diagnosis of clinical conditions that would give the 2D images of a 3D structure and had narrow exposure latitude. However, with the advent of modern diagnostic techniques, such problems have been largely resolved. There are a number of imaging techniques like ultrasonography, computed tomography, nuclear medicine scintigraphy and magnetic resonance imaging that are currently available for clinical veterinary diagnosis. Each with its strengths and weaknesses. More than one technique therefore, may be used to compliment or supplement the findings of other techniques to arrive at a final diagnosis. The modern imaging diagnosis though well established in developed countries across the globe, it is yet to be embraced or remains in its infancy stage in veterinary curriculum and practice in Nigeria; due to heavy initial investment and maintenance costs, lack of professionals, requirements of specialized skilled technical staff to manage the machines and the need for adjustable machines to accommodate the different species of animal. This study presents a brief review and update of the development, challenges and status of a diagnostic imaging technique -Magnetic Resonance Imaging in veterinary medical curriculum and practice in Nigeria.

The use of animals in scientific research dates back to 500 BC, with research from Greece by Alcmaeon and other temporary scientists. Techniques for dissecting living animals were improved by Galen of Pergamum and his experiments were later valuable in the discovery of blood circulation in the16th century . Until the 18th century humans were envisaged as the only alternative to animals in scientific research, and it was advocated that criminals in particular should be the subjects of vivisection. By the 19th century, however, even the use of cadavres came under regulation 1 .Claude Bernard and other leading scientists defended the focus on animal experimentation, which increased its use. A hard blow has been dealt on animal model based research by the reduced funding and support in favor of non-animal model techniques which include synthetic models, cadaver models as well as computer simulations, these styles of instructions
