A New MRI Technique for Peripheral Nerve Detection and Delineation - Specifically the Genicular Sensory Nerves Around the Knee
Genicualr ablation / block is a growing trend as a clinical solution for chronic pain in osteoarthritic knees (ref. 1). Much like facet block in the spine, it denervates the sensory branch and relieves pain for several months to 2 years (refernce2).
Efficacy of genicular ablation varies, mostly due to the variations in genicular nerve anatomical locations, as ablation sites are usually chosen by bony land marks, without visualization of the nerves (ref. 1, method).
A new approach for optimized MRI acquisition technique is described, with snap shots of results, enabling visualization of the genicular nerve pathway, thus allowing in the future better placement of ablation instrumentation. The technique can be utilized for other peripheral nerves as small as 1mm in diameter.
