“…Results of 1 study 40 indicate that identification of cartilage lesions in equine MCPJs by evaluation of images obtained by high-field (1.5-T) MRI or sMRI systems was much less accurate than histologic examination. In another study, 41 the sensitivity and specificity of 3-T MRI for identification of articular cartilage defects in the MCPJ of non-Thoroughbreds were 41% and 93%, respectively, compared with gross anatomic evaluation. Investigators of those studies, 39-42 recognizing the limitations of the use of 1.5-T and sMRI systems for identification of cartilage lesions in the equine MCPJ, did not describe a grading scale for articular cartilage changes.…”

“…[36][37][38] Finally, the lack of physical separation between adjacent cartilage surfaces in both the human tibiotalar joint and equine MCPJ makes it difficult to identify the opposing cartilage surfaces as distinct structures. [38][39][40][41] It is recommended that suspected cartilage lesions in the human tibiotalar joint 38 and equine MCPJ 39-42 be evaluated with a 3-T MRI system because the aforementioned functional and structural characteristics of the cartilage layers and the imaging difficulties they produce make imaging of those joints fundamentally susceptible to volume-averaging artifacts. Results of 1 study 40 indicate that identification of cartilage lesions in equine MCPJs by evaluation of images obtained by high-field (1.5-T) MRI or sMRI systems was much less accurate than histologic examination.…”

Articular cartilage is a critical joint tissue and its evaluation remains a diagnostic challenge in horses. Coupled with a poor capacity for healing, early degenerative changes in articular cartilage are difficult to characterise using routine diagnostic imaging evaluations. Both computed tomography (CT) and magnetic resonance imaging (MRI) provide volumetric joint assessment and highlight morphological and quantitative properties of articular cartilage, improving assessment of this essential tissue. While the use of CT and MRI for joint evaluation is not new, there still remains a shortage of literature and scientific studies on the ability of these methods to evaluate articular cartilage in the horse. This review article summarises current CT and MRI techniques capable of characterising equine articular cartilage, highlights recent advances in these techniques and discusses the numerous methods studied in human subjects that have been minimally investigated in horses. Imaging techniques are presented in terms of their capabilities of offering morphological and quantitative evaluation along with a discussion of their benefits and limitations. Finally, it summarises the current state-of-the-art approaches and identifies unmet clinical imaging needs to propel the advancement of articular cartilage and joint imaging in the horse.

“…With the technical progress in MRI magnets with field strengths of 3 Tesla become available in equine veterinary medicine (Gutierrez-Crespo et al 2013, Hontoir et al 2013). Higher field strengths bring along new possibilities, advantages in image acquisition like higher resolutions, thinner slices or shorter acquisition times in some sequences but also difficulties (Merkle andDale 2006, Chang et al 2008).…”

Summary:The nasal cavities and paranasal sinuses of 13 healthy horses of different breeds aged 4 to 20 years were examined under general anaesthesia using 3 Tesla magnetic resonance imaging (MRI). Horses were positioned in dorsal recumbency. T2-weighted images were obtained in a transversal and dorsal orientation as well as T1-weighted images and proton density weighted images in a transversal orientation. Images were examined for the visualization of the nasal cavities, paranasal sinuses and adjacent anatomical structures. Differences and similarities in the appearance of the anatomical structures in the different MRI sequences as well as inter-and intraindividual differences and similarities were documented. In four selected planes of the transversal oriented T2-weighted images the thickness of the venous plexus of the nasal mucosa of the left and right side could be measured in 12 horses. Planes and measurement points were chosen by defined anatomical landmarks. Visualized anatomical structures were well delineated in 3 Tesla magnetic resonance images. Inter-and intraindividual differences were present in the appearance of the nasal septum, the venous plexus of the nasal mucosa, the infraorbital canal and other structures in the examined healthy horses. The thickness of the venous plexus of the nasal mucosa was measured with up to 25.5 mm lining the spiral lamella of the ventral concha and the nasal meatus were entirely occluded by the nasal mucosa in some horses. Knowledge of the physiological appearance of anatomical structures in 3 Tesla MRI is fundamental in the use of this imaging modality as a diagnostic instrument. Interindividual differences in the appearance of anatomical structures are present in healthy horses and therefore not to be interpreted as pathologies in clinical cases.Keywords: MRI / horse / paranasal sinuses / nasal mucosa / upper airways / 3 Tesla Darstellung der Nasenhöhlen, Nasennebenhöhlen und angrenzender anatomischer Strukturen im 3 Tesla-Magnetresonanztomographen bei 13 gesunden Pferden Die Nasen-und Nasenebenhöhlen von 13 gesunden Pferden unterschiedlicher Rasse im Alter von 4 bis 20 Jahren wurden in Allgemeinanästhesie mit einem Magnetresonanztomographen der Feldstärke 3 Tesla untersucht. Die Pferde wurden in Rückenlage positioniert. Es wurden transversal und dorsal ausgerichtete Aufnahmen in einer T2-Gewichtung sowie transversal ausgerichtete Aufnahmen in einer T1-und einer Protonengewichtung erstellt. Die Bilder wurden systematisch betrachtet und ausgewertet. Im Rahmen der Auswertung wurde besonders auf die Darstellung der anatomischen Strukturen im Bereich der Nasen-und Nasennebenhöhlen geachtet. Im Zuge der Betrachtung wurde die Darstellung der verschiedenen anatomischen Strukturen in den unterschiedlichen Aufnahmesequenzen beurteilt und Ähn-lichkeiten und Unterschiede zwischen den Sequenzen dokumentiert. Auch inter-und intraindividuelle Unterschiede und Übereinstimmungen wurden dokumentiert. In vier ausgewählten Schnittebenen der transversal orientierten T2-gewichteten Sequ...
