For CSF to flow at the rate of several centimeters per second or more, it is necessary for brain pulsation to synchronize with the cardiac systole and diastole to make the CSF move to-and-fro between the cranium and the spinal cavity. Another eight patients were studied with ECG-triggered ...
the brain cells contract. After shrinking, the gaps between cells will widen, which is more conducive to CSF cleansing. Because it provide more space for the flow of CSF, which contains numerousglial cells(胶质细胞)tha...
The spinal CSF and cerebral blood flow measured at intracranial and extracranial levels were quantified using cine phase-contrast magnetic resonance imaging (PC-MRI) in 38 healthy young adults. Subsequently, CSF_VC and CB_VC were calculated, and by linear regression analysis (R2 and slope), the...
reduction, often used to suppress cerebrospinal fluid (CSF) flow artifacts in spinal magnetic resonance imaging (MRI), can be switched off to make the CSF flow voids within syrinx (syringomyelia) and within aqueduct [normal pressure hydrocephalus (NPH)] more obvious (thus confirming CSF flow). ...
The CSF flow comprises the slow flow forced out of the ventricles by the production of CSF itself, which is termed bulk flow, and the rapid movement of CSF propelled by the brain pulsations, which is termed to-and-fro flow. A disturbance of CSF circulati
Improved Visualization of Cervical CSF Flow using Balanced Steady State Free Precession Phase Contrast MRI IntroductionNoninvasive measurements of cerebrospinal fluid (CSF) flow in the brain with MR imaging have enabled an increased understanding of life threate...

We established changes of brain and spinal fluid dynamics over an age range from 5–40 years. The application of RT-PC MRI in clinical care may improve our understanding of CSF flow pathology in individual patients. 展开 关键词: BLOOD flow VENA cava inferior MAGNETIC resonance imaging ADULTS ...
Upward CSF flow into the head during inspiration counterbalances venous flow out of the brain. Here, we investigated CSF motion along the spinal canal by real-time phase-contrast flow MRI at high spatial and temporal resolution. Results reveal a watershed of spinal CSF dynamics which divides ...

Levels of immunoreactive cysteinyl-leukotrienes in CSF after subarachnoid haemorrhage correlate with blood flow-velocity in TCD Lipid peroxidation and enhanced arachidonic acid metabolism is activated after blood-brain cell contact. Previous studies have indicated that cysteinyl-leu... M Winking,HW Müller...
