(A-D) Cisternographic images of head and entire spine.
(E) Lower left panel shows left lateral cisternographic images of head and cervical spine.
(F,G) Shows axial view CT-myelograms. Note cephalad expansion of intrathecally-introduced radioisotope and multiple meningeal diverticula and dilated nerve root sleeves (arrows). Sequential imaging at less than 20 minutes, at 2 hours, at 4 hours, and at 24 hours shows that radioactivity even at 24 hours does not reach the sagittal vertex area or much of the cerebral convexities.
