Blood flow artifacts in MRI refer to image distortions or signal loss caused by the motion of blood within vessels. Blood flow artifacts is often seen in regions where there is a pulsatile blood flow such as the heart, large vessels, and sometimes the brain. Blood flow can create several ty...
Due to the susceptibility of a sub-type of this disease1 and CSF flow in general2 to gravitational pull, imaging the patient in the recumbent position is less than ideal. The goal of this work is to explore for the first time the utility of upright MRI in the diagnosis of CMI....
Frequency analyses of CSF flow on cine MRI in normal pressure hydrocephalus. Eur Radiol. 2003;13:1019 - 1024.Miyati T, Mase M, Banno T, Kasuga T, Yamada K, Fujita H, Koshida K, Sanada S, Onoguchi M . Frequency analyses of CSF flow on cine MRI in normal pressure hydrocephalus . ...
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 circulation in the craniospinal cavity often...

We hypothesize that in this situation of low volume, a larger CSF flow and spinal cord motion at the upper spine can be measured by noninvasive phase contrast MRI.MethodsA prospective, age-, sex-, and body mass index (BMI)-matched controlled cohort study on patients with SIH presenting ...
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 simulationsFLOW measurementPurpose To develop and validate a noninvasive imaging technique for accurately assessing very slow CSF flow within shunt tubes in pediatric patients with hydrocephalus, aiming to identify obstructions that might impede CSF drainage. Theory and Methods A simulation of shunt...
