longitudinal magnetisation

longitudinal magnetisation

An MRI term for the component of the net magnetisation vector that moves in the direction of the static magnetic field. After RF excitation, the component returns to equilibrium at a rate defined by the time constant T1.

The signal intensity improves with the higher value of TR by allowing maximum recovery of longitudinal magnetisation.
Sine TR controlled the recovery of longitudinal magnetisation of tissues, at higher values of TR the difference between longitudinal magnetisation was more prominent among tissues.
