Gradient Echo Pulse Sequence in Magnetic Resonance Imaging

This Demonstration shows a spoiled gradient echo pulse sequence from a magnetic resonance imaging (MRI). The "repetition time" (in seconds) and "flip angle" are parameters that can be controlled on an MRI machine to yield scans with different contrast between tissues. This Demonstration examines an image of the brain with the tissues: cerebrospinal fluid, gray matter, white matter, fat, muscle, skin, dura, marrow and vessels at a magnetic field of 3.0 T.
