WebNormal CSF flow is a consequence of both transmitted choroidal arterial pulsations and bulk flow resulting from continuous CSF production. Radionuclide CSF FS, or so-called … The study of CSF flow became one of Phase-contrast MRI's major applications. The key to Phase-contrast MRI (PC-MRI) is the use of a bipolar gradient. A bipolar gradient has equal positive and negative magnitudes that are applied for the same time duration. The bipolar gradient in PC-MRI is put in a sequence after RF excitation but before data collection during the echo time of the generic MRI modality. The bipolar lobe must be applied in all three axes to image flow in …
