The CSF flow waveform in both the supine and upright posture were within the normal range (Fig. 2a). However, the spinal cord diastolic peak velocity was larger and earlier than normal in the supine posture (Fig. 2b). This abnormal motion was also visually evident in the cine movie...
Use flow compensation techniques: Flow compensation techniques, such as bipolar gradients or gradient moment nulling, can be used to compensate for the effects of CSF flow, reducing the artifact. Change the imaging plane orientation: Changing the imaging plane orientation can sometimes help to avoid ...

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...
Decline of intrinsic cerebrospinal fluid outflow in healthy humans with age detected by non-contrast spin-labeling MRI Background Clearance of cerebrospinal fluid (CSF) is important for the removal of toxins from the brain, with implication for neurodegenerative diseases. I... V Malis,W Bae,A Ya...
We describe an analysis method that characterizes the correlation between coupled time-series functions by their frequencies and phases. It provides a unified framework for simultaneous assessment of frequency and latency of a coupled time-series. The an
Magnetic resonance imaging (MRI) studies have found thalamic abnormalities in major depressive disorder (MDD). Although there are significant differences in the structure and function of the thalamus between MDD patients and healthy controls (HCs) at the
