- “Flow Void Sign”: Flow Artifact on T2-Weighted MRI Can Be an Indicator of Dural Defect Location in Ventral Type 1 Spinal CSF Leaks
Type 1 CSF leaks are commonly associated with ventral predominant epidural fluid. On 2D T2-weighted and STIR images, CSF-flow artifact in the anterior subarachnoid space and/or the adjacent epidural fluid collection at the level of the dural defect is caused by CSF-flow and may permit accurate prediction of the site of the CSF leak noninvasively.
- Alternative Venous Pathways: A Potential Key Imaging Feature for Early Diagnosis of Sturge-Weber Syndrome Type 1
In this retrospective review of children with SWS, the most prevalent lesions at the first MRI were subarachnoid varicose network and transmedullary veins. The dilated venous channels are an early compensatory mechanism, preceding abnormal pial contrast enhancement, atrophy, and calcification.
