Rapid three-dimensional MR imaging method for tracking a bolus of contrast agent through the brain.
Journal Article (Journal Article)
A gradient-echo three-dimensional magnetic resonance imaging technique (principles of echo shifting with a train of observations, or PRESTO) is presented for use in tracking a bolus of paramagnetic contrast agent through the brain. The approach combines a segmented echo-planar type of acquisition with echo shifting, which leads to echo times that are longer than the repetition time. Unlike echo-planar imaging, the method maintains image resolution despite drastic T2* changes and frequency shifts.
