“…Several papers describing the normal CT (Zotti and others 2009, Van Caelenberg and others 2010a, Stamatova and others 2013), MRI (Van Caelenberg and others 2010b) and radiographic (Hammond and others 2010) features in this species have, however, been published recently. The ultrasonographic features of the prostate and bulbourethral glands (Dimitrov and others 2011) and the vesicular glands (Dimitrov and others 2013) of the rabbits have also been described.…”

This study aimed to determine the ultrasonographic features and reference values of the abdominal anatomy in mixed-breed dwarf rabbits. Complete abdominal ultrasonographic examination was performed in 21 mixed-breed rabbits (12 males and 9 females) referred for examination to the Department of Animal Medicine, Production and Health, University of Padua, Italy. All animals were sedated during the procedure. The ultrasonographic anatomy of the abdomen was determined, including measurement (mean±SD) of the right kidney (length 2.87±0.34 mm; width 1.62±0.17 mm; height 1.66±0.14 mm) and left kidney (length 2.86±0.33 mm; width 1.72±0.19; height 1.58±0.15 mm), left adrenal gland (width 0.38±0.11 mm; length 0.71±0.14), right adrenal gland (width 0.34±0.08 mm; length 0.73±0.15 mm) and thickness of the walls of the stomach (0.10±0.01 mm), pylorus (0.28±0.04 mm), duodenum (0.19±0.04 mm), sacculus rotundus (0.22±0.06 mm), caecum (0.08±0.01 mm), appendix (0.19±0.04 mm), spiral loop of the ascending colon (0.14±0.04 mm) and distal colon (0.10±0.02 mm). A significant positive correlation between bodyweight and kidney size, adrenal gland length, stomach wall and sacculus rotundus wall was detected.

“…Em contrapartida, os equipamentos de alto campo apresentam maior custo e podem exibir artefatos de imagem. No trabalho realizado por Van Caelenberg et al (2011), em que foi realizada a descrição anatômica dos tecidos moles da cabeça de coelhos normais, foi utilizado um equipamento de 0,2 T de baixo campo. Os autores citaram que, embora se tenha conseguido imagens de boa qualidade, foi gasto um tempo relativamente longo para a aquisição de todas as sequências necessárias ao exame, com cerca de 30 minutos de duração.…”

ABSTRACT. - This study aimed to determine the characteristics and applicability of magnetic resonance imaging (MRI) in the evaluation of autogenous osteochondral graft in intact or macerated format, with or without insulin-like growth factor type 1 (IGF-1) used in repair of cartilage lesions induced in rabbits. Nine New Zealand rabbits were used, in which 18 stifle joints underwent grafting procedure in the femoral trochlear groove. These were divided into four groups, referred as intact osteochondral graft + IGF-1 (n=5), intact osteochondral graft + saline solution (n=4), macerated osteochondral graft + IGF-1 (n=5) and macerated osteochondral graft + saline solution (n=4). Animals were euthanized 12 weeks after surgery and the joints were subjected to MRI using a high magnetic field scanner of 1.5 Tesla. In addition, samples of grafting sites were subjected to anatomopathological examination. The MRI was effective as a noninvasive method to evaluate the repair tissue in osteochondral grafts in articular cartilage of the femur of rabbits by providing complementary data to macroscopic and histological examinations. Through these images and anatomopathological examinations satisfactory results were observed in relation to the repair process of autogenous osteochondral grafts in cartilage of rabbits, regardless of its format or the addition of IGF-1. RESUMO.-Este trabalho teve o objetivo de determinar as características e a aplicabilidade do exame de ressonância magnética na avaliação de enxerto ostecondral autógeno, em formato íntegro ou macerado, associado ou não ao fator de crescimento semelhante à insulina tipo 1 (IGF-1), utilizado no reparo de lesões induzidas na cartilagem articular de coelhos. Foram utilizados 9 coelhos da linhagem Nova Zelândia, em que as 18 articulações fêmoro-tíbio-patelares foram submetidas à enxertia osteocondral autógena no sulco troclear femoral. Estas foram divididas em quatro grupos, denominados como enxerto osteocondral íntegro + IGF-1 (n=5), enxerto osteocondral íntegro + solução fisioló-gica (n=4), enxerto osteocondral macerado + IGF-1 (n=5) e enxerto osteocondral macerado + solução fisiológica (n=4). Os animais foram eutanasiados em 12 semanas após a cirurgia e as articulações foram submetidas ao exame de ressonância magnética utilizando um aparelho scanner de 1,5 Tesla de alto campo magnético. Além disso, amostras dos locais de enxertia foram submetidas aos exames anatomopatológicos. O exame de ressonância magnética mostrou--se eficaz como um método não invasivo para avaliação do tecido de reparação em enxertos osteocondrais na cartilagem articular do fêmur de coelhos, fornecendo dados complementares aos exames macroscópicos e histológicos.

“…Rabbits have accessible, discrete, paired, palatine tonsils demonstrated in low‐field magnetic resonance imaging (MRI) and computed tomography, and they have been previously used for studies of palatine tonsil size, function, and histology . Healthy 16‐week‐old New Zealand white male rabbits, weighing between 2.78 kg and 3.8 kg, were used as the model for this study.…”
