“…Ischemic infarcts most commonly affect specific vascular territories. Haemorrhagic strokes can have a varied appearance, primarily based on the duration of the haemorrhage and alteration in blood haemoglobin (Garosi et al, 2001). Diffusion-weighted MR imaging sequences allowing the mapping of water molecules can aid in the diagnosis of infarcts.…”

“…Thus, MR imaging has become the choice modality in the diagnosis of most orthopaedic conditions and a one stop shop for diagnosis of most chronic equine lameness. MR imaging reveals the brain with greater clarity than ever before, and ante mortem diagnosis of neurologic conditions, such as intracranial neoplasia (Kraft et al, 1997;Garosi et al, 2001;Cerda-Gonzalez et al, 2009), has become increasingly common. In spine studies, MR imaging reveals conditions that hitherto could not be accurately diagnosed ante mortem and this has facilitated the study of their pathophysiology for example syringohydromyelia and fibrocartilaginous embolism (Couturier et al, 2008;Cerda-Gonzalez et al, 2009).…”

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.

“…Dos exames complementares utilizados para confirmar a disfunção vestibular, a análise do líquido cerebroespinhal (LCE) e do exame radiográfico simples não costumam permitir um diagnóstico definitivo (Bailey & Higgins 1986). Na maioria dos casos, o diagnóstico de distúrbios vestibulares depende de exame neurológico detalhado, de exames de imagem mais avançados (tomografia computadorizada e ressonância magnética) (Garosi et al 2001, Kent et al 2010) e, ocasionalmente, da resposta evocada auditiva do tronco encefálico (REAT). No entanto, o custo e a disponibilidade desses métodos muitas vezes limitam a investigação dos diagnósticos diferenciais (Strain 2010).…”

As doenças de asininos e muares na região semiárida do nordeste do Brasil foram avaliadas em um estudo retrospectivo dos 258 atendimentos realizados no Hospital Veterinário da Universidade Federal de Campina Grande no período de janeiro de 2002 a dezembro de 2012. Dos prontuários desses animais foram coletados dados referentes a identificação, anamnese, exame clínico, diagnóstico, protocolo de tratamento e evolução dos casos. Durante o período analisado foram atendidos 200 asininos e 58 muares. Os sistemas afetados foram os seguintes em ordem de frequência: tegumentar, 88 casos; musculoesquelético, 78; digestivo, 36; nervoso, 23; reprodutor, 15; e respiratório, 6. Oito animais foram atendidos para avaliação pré-cirúrgica e encaminhados para orquiectomia; três animais tiveram diagnóstico inconclusivo e um animal sofreu acidente por picada de abelha. As principais enfermidades diagnosticadas nos asininos foram feridas traumáticas (33/200), fraturas (27/200) e cólica (14/200). Para os muares os principais diagnósticos foram cólica (8/58) e feridas traumáticas (6/58). Em ambas as espécies as fraturas foram a principal causa para realização de eutanásia (22/200 asininos e 3/58 muares). Conclui-se que a maioria das doenças diagnosticadas estão associadas com maus tratos ou falta de atenção com os animais e devem ser prevenidas mediante campanhas de conscientização e educação dos proprietários e tratadores, esclarecendo sobre a importância das melhorias do manejo e do bem-estar dos animais.

“…The healthy tympanic bulla gives an attenuation signal on all sequences. Free fluid in the middle ear is isointense to the brain on T1-weighted sequences and hyper-intense on T2-weighted sequences (Garosi et al 2001). The MRI modality allows the diagnosis of different disorders of the membranous labyrinth.…”

“…The MRI modality allows the diagnosis of different disorders of the membranous labyrinth. In chronic inner ear inflammation, the fluid which appears in the internal ear suppresses the signal in T2-weighted sequences (Garosi et al 2001). Labyrinthosis may increase gadolinium enhancement, as a result of inflammation or decrease the haemoperilymphatic obstacle (Vignaud et al 1995).…”

Otitis media is a common disease in clinical veterinary practice. Although low-field magnetic resonance imaging reports for otitis media in dogs exist, in cats detailed information is missing. Radiography is helpful in diagnosing chronic inflammation, but may be insufficient during the initial phase of inflammation. For this reason, this report describes the magnetic resonance findings in two cats with otitis media. In both cases, middle ear empyema was detected. Magnetic resonance imaging of middle ear disorders in cats should contain pre-and post-contrast T1-weighted sequences in the dorsal and transverse planes, a T2-weighted sequence in the dorsal and transverse planes and a fluid-attenuated inversion recovery sequence in the dorsal or transverse planes. On pre-contrast T1-weighted images, the empyema had an intensity similar to that of brain tissue with a delicate hyper-intensity in the middle. On post-contrast T1-weighted images, the material had non-uniform enhancement in the dorsolateral compartment and circumference enhancement in the ventromedial compartment of the tympanic bulla with a hypo-intense centre. On T2-weighted images, the mass had heterogeneously increased signal intensity to brain tissue, but was less intense than cerebrospinal fluid. In the fluid-attenuated inversion recovery sequence, the pathological lesion was distinctly hyper-intense in comparison to other tissues with a narrow area of increased signal intensity in the middle of the ventromedial tympanic bulla compartment. Magnetic resonance imaging is commonly used for the visualisation of different disorders of the membranous labyrinth and allows the differentiation of chronic hematomas, empyemas and middle and internal ear neoplasia. The recommended magnetic resonance protocol of the middle ear should include pre-and post-contrast T1 sequences in the dorsal and transverse planes, the T2 sequence in the dorsal and transverse planes and the fluid-attenuated inversion recovery sequence in the dorsal or transverse planes.
