- Safety and Technical Performance of Bilateral Decubitus CT Myelography Using Standard versus Increased Intrathecal Iodinated Contrast Volume
In this retrospective study, the authors assessed the tolerability and technical performance of increased intrathecal doses (20 mL) of myelographic contrast compared with standard doses (10 mL). They found that the increased volume of intrathecal contrast was well-tolerated and improved the technical performance of LDCTM.
- “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.
