RT Journal Article SR Electronic T1 Noninvasive MR Cisternography with Fluid-Attenuated Inversion Recovery and 100% Supplemental O2 in the Evaluation of Neurocysticercosis JF American Journal of Neuroradiology JO Am.

YR 2004 UL http://www.ajnr.org/content/25/2/295.abstract AB Summary: We describe an MR protocol for the noninvasive imaging of the subarachnoid space, which we use in patients with suspected neurocysticercosis in this space. It consists of a fluid-attenuated inversion recovery sequence performed 5 minutes after the continuous inhalation of 100% O2 with a resultant increase in the signal intensity of the CSF that leads to a greater conspicuity of cyst walls in relation to the cortex and the extraventricular CSF.
