This Demonstration shows a spin echo pulse sequence in magnetic resonance imaging (MRI). The "echo time" can be manipulated on an MRI machine to yield scans with different contrast between tissues. This Demonstration examines an image of the brain showing the tissues: cerebrospinal fluid, gray matter, white matter, fat, muscle, skin, dura, marrow and vessels at a magnetic field of 3.0 T.
