Cine Phase Contrast imaging is used for the evaluation of CSF flow in a number of pathological states. Compared with the Time-Of-Flight angiographic technique, many trainees and practicing radiologists are less familiar with the physics of Phase Contrast imaging. Understanding the basic physics will assist practitioners in interpreting and optimizing these studies. As CSF flow imaging is performed on a relatively infrequent basis, a review of some common clinical applications and pathological findings will aid practicing radiologists in providing meaningful image interpretation.
