Abstract
Balanced SSFP sequences do not suffer from spin saturation effects that result in signal loss for tissues with long T1. Their contrast is therefore optimal for the imaging of fluids (blood and CSF) and flow quantification, especially when inflow enhancement effects cannot be exploited, as in three-dimensional sequences. In this work, a three-dimensional, three-directional time-resolved phase contrast bSSFP sequence is presented, along with methods to minimize the artifacts commonly associated with bSSFP sequences, and the application to the study of cerebro-spinal fluid circulation is demonstrated.
