CT Myelography Complete Spine Although CT myelography complete spine can detect epidural contrast collections suggestive of dural defect or leaking meningeal diverticulum, MRI complete spine optimized with fluid sensitive sequences has been shown to detect epidural collections with equal sensitivity and is a preferred initial imaging option over CT myelography complete spine because it avoids the need for lumbar puncture [34-36]. CT Myelography Dynamic Complete Spine There is no relevant literature to support the use of dynamic CT myelography complete spine in the initial imaging of suspected SIH. Dynamic CT myelography plays an important role in the subsequent imaging workup of SIH after the initial brain and spine imaging [37,38]. Results from an initial spine MRI or conventional CT myelogram provide useful information on how a subsequent dynamic CT myelogram will be performed, such as prone positioning for suspected ventral dural defect or decubitus positioning for suspected leaking meningeal diverticulum or CSF-venous fistula [24,37-39]. Dynamic CT myelography involves an initial scan followed by delayed phase scans in immediate succession and, when performed in the decubitus position, may require 2 separate contrast injections due to the transient temporal characteristics associated with CSF-venous fistula visualization as well as limitations in contrast dosing [40-44]. DTPA Cisternography Although diethylenetriamine pentaacetate (DTPA) cisternography can detect epidural collections suggestive of dural defect or leaking meningeal diverticulum, MRI complete spine optimized with fluid sensitive sequences is typically the preferred initial imaging option over DTPA cisternography complete spine because it avoids the need for lumbar puncture and has superior spatial resolution for lesion localization [45,46]. MR Myelography Complete Spine There is no relevant literature to support the use of MR myelography complete spine in the initial imaging of suspected SIH.
