WebMar 1, 2003 · Both conventional spin-echo MR imaging and directional flow determination with cine phase-contrast MR imaging have been used to describe flow of CSF in the brain, in a variety of clinical situations (1–10).These studies are noninvasive; however, the spin-echo techniques are less accurate and the cine format when used alone is subjective.

WebThe calculated CSF stroke volume and the aqueductal CSF flow void score were compared with the surgical results. Results: All 12 patients with CSF stroke volumes greater than 42 microL responded favorably to CSF shunting. Of the six patients with stroke volumes of 42 microL or less, three improved with shunting while three did not. WebThe evaluation of CSF flow with flow-sensitive MR images was reported previously. Most of these reports have focused on physiologic flow patterns of CSF or abnormal flow patterns, especially in obstructed CSF pathways (30–33). Only a few studies concern the flow dynamics in ACs. Hoffmann et al (22) reported WebOBJECTIVE. Manual segmentation of the aqueduct for CSF flow analysis may induce measurement variability. The aim of our study was to assess observer agreement of manual segmentation and to compare the repeatability and accuracy of different flow parameters in differentiating normal-pressure hydrocephalus (NPH) from brain atrophy. georgia election results greene
