Magnitude of chemical shift (in millimeters) associated with selection pulse with a given bandwidth at for a 100mm-wide selected region. The standard 180 degree pulses used in commercial sequences are typically 1kHz, spatial-spectral pulses are in the range of 3–5kHz and the most recent LASER pulses are in the range of 5–20kHz.
