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...

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...
(SA Instruments). The imaging protocol consisted of T2-weighted 2D rapid acquisition with relaxation enhancement (2D-RARE) for reference spatial planning with the following settings: repetition time (TR) = 4000 ms, effective echo time (TE) = 60 ms, number of averaging (NA) = ...
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 ...
CSF pulsatile flowECG triggering (gatingIn a retrospective study of the MRI images of 289 neurosurgical patients, a loss of the signal intensity (the signal void phenomenon, SVP for short) of the cerebrospinal fluid in the mesencephalic aqueduct was observed in 77 patients. The SVP, which ...
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....
However, the relationships between CSF flow, cord motion and degree ofcompression or CSM symptoms are not well known. The purpose of the study was to compare velocity patterns of CSF and cordbetween CSM subjects and controls.MethodsMRI Experiment: 14 subjects diagnosed with CSM as char...
