Hi....sorry I was away....the CINE MRI is a moving study of the CSF flow....in real time....to see if it pulsates along with ur BP and contrast is used, it is done in 2 parts, ,the first, is similar to all other MRI's u have had, the 2nd uses a BP clip or leads and contrast and instead of pics takes a "movie" of the CSF.
An MRA is a specific type of MRI that captures images of the body's blood vessels.
An "MRA" uses dye-contrast medium to examine the intricacies of the vascular system and the microcirculation. The "MRI" provides a better view of the physical structures and abnormalities. They are complimentary. A flow study can be performed with dopplar imaging (not an MRI) or with dye contrast.
