Magnetic resonance signal

signal(s) received during an NMR experiment. In MR imaging, the MR signal is encoded using varying gradient fields so that the position of the spins yielding the signal can be reconstructed. In addition, the signal can be encoded for other system properties like spin velocity, or for chemical shift. This latter property is encoded when performing MR spectroscopy or chemical shift imaging CSI .
