Dynamic CT

The meeting presentation was led by Natasha Werpy. The primary focus of the presentation was on the use of dynamic CT imaging for assessing cervical spine conditions in horses. The procedure aims to replace traditional radiographic myelograms with CT imaging to provide more accurate and detailed images of the cervical region. The process involves specific positioning to ensure the best imaging results, starting with caudal flexed views, which are identified as the most challenging due to the need to avoid lateral flexion that could result in false interpretations.

Positioning during CT imaging is critical to obtaining accurate diagnostic information. The discussion highlighted the need for careful alignment of the horse’s neck to prevent lateral flexion that could simulate or obscure spinal cord compression. Techniques such as using air-inflated bags for fine-tuning neck positioning were discussed to maintain the correct alignment throughout the imaging process. This meticulous approach ensures that the images reflect true anatomical conditions rather than artifacts caused by positioning.

A significant portion of the discussion revolved around interpreting imaging results, particularly distinguishing between contrast attenuation and actual spinal cord compression. The group explored the implications of transient compression, which might not show histological changes yet could still be clinically significant. The necessity of correlating imaging findings with clinical signs was emphasized, as was the potential variability in spinal cord size and shape due to positional changes, which could affect interpretation.

The meeting acknowledged the gaps in current knowledge, particularly regarding the histological correlation of imaging findings and the effects of transient compression. The need for further research into dynamic MRIs and histopathological studies was identified as crucial for developing more accurate diagnostic criteria. Additionally, discussions on exploring nerve conduction studies and other diagnostic methods to better understand and diagnose cervical spine conditions were proposed.

The meeting also briefly addressed the need for ongoing collaboration with insurance companies regarding equine health assessments. Plans to establish a regular forum for discussing insurance-related issues at professional meetings were outlined, aiming to facilitate better understanding and management of veterinary claims and procedures.
