These include superior spatial resolution, high temporal resolution, and inherent spectral imaging capabilities. Recently, photon-counting CT myelography was described as an effective technique for the detection of CSF-venous fistulas, a common cause of spontaneous intracranial hypotension. It is likely that photon-counting CT myelography will also have advantages for the localization of dural tears, a separate type of spontaneous spinal CSF leak that requires different myelographic techniques for accurate localization. To our knowledge, prior studies on photon-counting CT myelography have been limited to techniques for detecting CSF-venous fistulas. In this technical report, we describe our technique and early experience with photon-counting CT myelography for the localization of dural tears.CTMCT myelographyDSMdigital subtraction myelographyEIDenergy-integrating detectorPCCTphoton-counting CTPC-CTMphoton-counting CT myelographySIHspontaneous intracranial hypotensionSRstandard resolutionUHRultra-high-resolutionVMIvirtual monoenergetic image
