The thought here is to collect various instructive artifacts and bad data sets. Just a thought.
In a few frames, this seems to be massive subject motion, like a cough. But in many places, it's
just a huge global intensity modulation that flickers through alternate slices in an interleaved
data acquisition. This is the worse of the 2 (8-minute) runs. Pulse sequence was a pretty
standard pulse sequence: 64 x 64 matrix, 35 slices with 2s TR, 25ms TE. slice thickness 2
mm w/ 75% gap; FOV of 224 x 224, providing 3.5 mm isotropic resolution.
