Cerebrospinal fluid flow measured by phase-contrast cine MR.
PURPOSE This prospective study was designed to establish the temporal and quantitative relationship between blood flow and cerebrospinal fluid (CSF) flow using a phase-contrast cine MR pulse sequence. METHODS A cine phase-contrast MR pulse sequence using peripheral gating was used to measure CSF flow direction and velocity. Data were acquired continuously and interpolated into 16 images throu...
متن کاملNormal and Abnormal Cerebrospinal Fluid Dynamics Evaluated by Optimized Cine Phase-contrast MR Imaging
The NPH group could be further divided into hyperand hypodynamic groups when compared with the normal agematched subjects. Vmax of the control group was significantly higher than that of the hypodynamic-NPH group (1.92 ± 1.11 cm/s, p < 0.001) and lower than that of the CH group (p < 0.007) and of the hyperdynamicNPH group (10.52 ± 0.23 cm/s, p < 0.001). With optimized parametric setting, two-di...
متن کاملThe role of cerebrospinal fluid flow study using phase contrast MR imaging in diagnosing idiopathic normal pressure hydrocephalus.
BACKGROUND The purpose of this prospective study was to identify the ability of cerebrospinal fluid flow study using phase contrast MR imaging to replace the invasive methods currently used to establish the diagnosis of idiopathic normal pressure hydrocephalus (iNPH). MATERIALS AND METHODS Between January 2003 and April 2005, 61 patients with clinical symptoms fitting the Hakim triad and a di...
متن کاملAnalysis of cerebrospinal fluid flow waveforms with gated phase-contrast MR velocity measurements.
PURPOSE To analyze the characteristics of normal cerebrospinal fluid (CSF) flow waveforms and to relate them to the arterial input and venous output flow waveforms in healthy volunteers. METHODS Cine phase-contrast MR was obtained in 17 volunteers. The temporal velocity information from the cervical pericord CSF spaces, basal cisterns, and aqueduct, as well as the internal carotid and vertebr...
متن کاملCerebrospinal fluid shunts: flow measurements with MR imaging.
The authors describe a technique for determination of shunt patency by quantifying cerebrospinal fluid shunt flow rates with magnetic resonance (MR) imaging. This method uses a modified clinical sequence that is both sensitive to slow flow perpendicular to the imaging plane and capable of achieving oblique angles with a 4-cm field of view. Velocity-dependent phase images were used to quantify f...
