Recent advances in MRI techniques have enabled us to visualize the movements of craniospinal fluid using fast imaging with heart triggering. This is referred to as MRI Cine technique with multiphase imaging. Using this method, signal changes are observed in a heart cycle. We evaluated MRI signals...
Flow compensation, a gradient pulse used for artifact 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...
Coronal T2-weighted magnetic resonance imaging (MRI) has been reported to be a useful technique for the localization of both spontaneous and traumatic CSF (cerebro spinal fluid) fistulae. We reviewed the magnetic resonance imaging (MRI) scans of 50 patients with temporal lobe epilepsy in whom suc...

Functional Imaging Using 3D High-sampling-Efficiency Technique (SPACE) versus Conventional CSF Flow Techniques in Patient with Hydrocephalus at 3 Tesla CONCLUSION 3D-T2SPACE should be the method of choice as a stand-alone sequence for the evaluation of AP in hydrocephalus. Due to the high accuracy...
Since the introduction of cardiac gated gradient echo sequences in MRI, the noninvasive study of intracranial cerebrospinal fluid (CSF) pulsations became possible [2, 5]. Especially in hydrocephalic patients disturbances of CSF flow in the mesencephalic aqueduct may be of clinical importance in ...

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 ...
For this purpose, the spinal CSF and cerebral blood flow measured at intracranial and extracranial levels were quantified using cine PC-MRI in healthy young adults. Subsequently, CSF_VC and CB_VC were calculated, and by linear regression analysis, the relationship between CB_VC at both levels ...
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
