Sacral Dural Tears in Spontaneous Intracranial Hypotension: Imaging Phenotype and Treatment Outcomes in a Multicenter Cohort.
Journal article AJNR Am J Neuroradiol · October 1, 2026 BACKGROUND AND PURPOSE: Sacral dural tears are an underrecognized cause of spontaneous intracranial hypotension, and their clinical behavior and response to treatment remain incompletely defined. We hypothesized that outcomes following epidural patching in ...

Journal article AJNR Am J Neuroradiol · October 1, 2026 BACKGROUND AND PURPOSE: CSF-venous fistulas (CVF) cause spontaneous intracranial hypotension (SIH) and can be treated with transvenous embolization (TVE). Although TVE has been shown to result in substantial symptomatic improvement, some patients may requi ...

Journal article AJNR Am J Neuroradiol · October 1, 2026 BACKGROUND AND PURPOSE: Photon-counting detector CT (PCD-CT) offers improved spatial resolution compared with conventional energy-integrating detector CT (EID-CT), but session-level dose comparisons in multiacquisition CT myelography (CTM) are limited. We ... Full text Link to item CiteRecent Grants
