“…Because elbow joint spaces may vary between different areas of the joint (De Rycke and others 2002) and because differences in the plane of reconstructed images may lead to variation in JSM (Holsworth and others 2003), a standard transverse CT slice template was used to plan the reconstructed images. This allowed rCT images to be formatted at consistent levels in the elbow and thus minimise error.…”

“…The authors speculated that it may be possible to measure joint spaces from reconstructed computed tomography (rCT) images of canine elbows which could allow more accurate detection of incongruency. Despite preliminary investigations (Geilen and others 2001, Holsworth and others 2003), the use of rCT in dogs has not been fully validated. The aim of the current study is to assess the accuracy and reliability of rCT for the measurement of elbow joint spaces in the dog.…”

OBJECTIVES: To assess the accuracy of reconstructed computed tomography for imaging canine elbow joint spaces.METHODS: Computed tomography scans of eight cadaveric elbows were obtained and reconstructed computed tomography images were formatted in the dorsal and sagittal planes. Humeroradial and humeroulnar joint space measurements were obtained from these images. Intra-observer and inter-observer variations in joint space measurements were assessed, as was the effect of specimen positioning (inter-image variation). After freezing, four elbows were sectioned in the dorsal plane and four in the sagittal plane. In addition to visual comparison of the frozen sections with reconstructed computed tomography images, joint space measurements were obtained from frozen sections and compared with those from reconstructed computed tomography images.Variation was assessed using statistical calculations and graphical techniques.RESULTS: Both inter-image and intra-observer analyses revealed good agreement and low variation between data sets. Interobserver correlation was only moderate, though variation was low.Visually, the reconstructed computed tomography images accurately reflected the frozen section anatomy. Agreement between frozen section and reconstructed computed tomography joint space measurements was good, with minimal variation.CLINICAL SIGNIFICANCE: These results indicate that reconstructed computed tomography is capable of accurately imaging elbow joint spaces and precise joint space measurements can be obtained.Reconstructed computed tomography may be useful for determining joint space measurements and detecting elbow incongruencies in dogs with elbow dysplasia.

“…Even when free fragmentation has been subsequently identified by arthroscopy or arthrotomy, identification of disease of the medial aspect of the coronoid process (MCD) has historically proven challenging despite use of diverse imaging modalities including radiography 2,[14][15][16][17] ; computed tomography (CT) 11,18 ; scintigraphy 19 ; and magnetic resonance imaging (MRI). 20 Typically, diagnosis is based on identification of secondary markers of degenerative joint disease in the absence of other discernable discrete pathologic changes.…”

“…A mensuração da incongruência radioulnar pode ser melhor realizada usando imagens tomográficas reconstruídas na região central do processo coronoide no plano oblíquo (Holsworth et al 2005). No estudo de Kramer et al (2006), as regiões central e ápice do coronoide não apresentaram diferenças significativas.…”

RESUMO: Este estudo teve como objetivo apresentar de forma detalhada dados morfológicos e morfométricos da articulação umerorradioulnar de cães de raça definida avaliados por meio de exames físicos, radiográficos e tomográficos. A amostra dessa pesquisa constituiu-se de 44 cotovelos de cães com idades variadas. Para análise de informações obtidas, o coeficiente kappa e de correlação interclasse e associação foram realizados. Constatou-se que o desempenho individual de cada projeção radiográfica teve pobre concordância com o exame tomográfico; não houve concordância entre os observadores para as mensurações do ângulo da incisura ulnar ao exame radiográfico e tomográfico. Porém houve boa/moderada concordância para mensuração da incongruência radioulnar no plano sagital entre os observadores. Concluiu-se que nenhuma das cinco incidências radiográficas foi superior para análise radiográfica, uma vez que cada projeção apresentou melhor identificação de um compartimento do cotovelo. Medidas ao exame tomográfico para incongruência radioulnar não apresentaram reprodutibilidade no plano de reconstrução frontal, entretanto no corte sagital apresentaram boa e moderada concordância entre os observadores e que a mensuração do ângulo da incisura ulnar não apresentou repetibilidade ao exame radiográfico e nem reprodutibilidade ao exame tomográfico. Esses resultados contribuem para melhor utilização de cada exame de acordo com a região a ser avaliada bem como ressaltam a necessidade da somatória de múltiplos exames de imagem para a correta avaliação desta afecção.
