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....

This study aims to establish reference values of CSF and venous flow in healthy subjects using RT-PC MRI and to determine their age dependency. Methods: RT-PC MRI was performed in 44 healthy volunteers (20 females, age 5–40 years). CSF flow was quantified at the aqueduct (Aqd), ...

imaging of the lower thorax). Peripheral pulse gating cannot be used for heart imaging due to the long and unpredictable delay between cardiac contraction and arrival of the pulse wave to the finger. Peripheral pulse gating is commonly used for peripheral MRA and for cine CSF flow studies, ...
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 ...
An interleaved velocity-sensitised fast low-angle shot pulse sequence was used to study cerebrospinal fluid (CSF) flow in the cerebral aqueduct, and suprat
