WebNov 11, 2016 · Previous studies have assessed CSF flow dynamic from different areas of aqueductus cerebri (Barkhof et al., 1994; Lee et al., 2004). According to some authors, the most accurate measurement of CSF flow is taken from the narrowest point of aqueductus cerebri at the level of colliculus inferior (Lee et al., 2004).

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.

Although CSF is a common angiographic finding, the long-term outcomes and mortality rates are still … 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. chime app for computer
