WebSagittal MR CSF cine-flow study (gradient-echo, TE, 7.9 ms; TR, 21 ms). This study was performed when the patient returned with ventriculomegaly 9 months after gamma knife treatment. CSF cine flow demonstrated free flow of CSF without evidence of intraventricular obstruction. The following clinical situations can benefit from CSF flow studies 2: 1. aqueduct stenosis 2. normal pressure hydrocephalus (NPH) 3. patency of third ventriculostomy 4. flow at the cervicomedullary junction (foramen magnum) 4.1. Chiari I malformation 4.2. achondroplasia See more Time-resolved 2D phase-contrast imaging with velocity encoding is the most widely used method and relies upon location-specific sequential application of a pair of phase encoding pulses in opposite directions. Stationary … See more Quantification of flow can be generated by defining a region of interest (e.g. cross-sectional area of the aqueduct of Sylvius) and charting velocity versus time, which is typically pulsatile … See more
