description: |
An MR noise scan often acquired alongside another MR scan.

These noise scans are acquired by disabling the radio frequency excitation,
while maintaining all other parameters from the associated scan.
These can be aquired using some other sequence with RF excitation removed

or as part of sequences that turns off RF at the beginning or end of a run.
For example a `bold` scan where a few volumes are acquired with RF off.
There is no consistent DICOM denotation for these scans so separating and
labeling noRF volumes would need to be done outside of automatic DICOM
conversion.
