The application of high-resolution cardiac phase resolved MRI (CINE) to directly visualize arachnoid adhesions for improved intervention planning in syringomyelia was investigated. It could be shown that high-spatial resolution (250mx500mx2mm) combined with 30 cardiac phases enabled direct visualization and quantification of the arachnoid adhesions. The position of the adhesions was verified during the intervention and post-interventional MRI was performed for assessment of the structure of the arachnoid adhesion after the microsurgical adhesiolysis procedure.
