Conebeam CT Myelography for the Detection of Spinal CSF Leaks

Spinal CSF leaks are the primary cause of spontaneous intracranial hypotension, with the most common types of leaks including CSF-venous fistulas and dural tears.¹ These leaks necessitate advanced myelographic techniques for accurate localization. Digital subtraction myelography is one such technique used at some institutions.² Although digital subtraction myelography has excellent temporal and spatial resolution, it does not provide high-resolution cross-sectional images. Here, we describe our technique for conebeam CT myelography performed immediately after digital subtraction myelography, which generates high-resolution cross-sectional images.^3-6 We illustrate how this technique enhances detection and characterization of some spinal CSF leaks.
