Stereoscopic MR cisternography

A time-reversed gradient echo pulse sequence, one of the MR imaging methods based on steady-state free procession of the excited spins, makes the cerebrospinal fluid (CSF) quite bright relative to the normal brain tissue. Using this sequence combined with a three-dimensional data set and maximum intensity projection method, which provided clear delineation of the spatial distribution of the CSF space in the brain. Though the clinical experience is limited, this technique is considered to be of value in the evaluation of CSF pathology.
