inversion recovery


in·ver·sion re·cov·er·y

a magnetic resonance pulse sequence in which a series of 180° magnetic field inversions is followed by a spin echo sequence for signal detection; of note, during recovery, the longitudinal magnetization vector passes through zero.

inversion recovery

An MRI term for an imaging sequence involving successive 180º and 90º pulses, after which a heavily T1-weighted signal is obtained. The inversion recovery sequence is specified in terms of inversion time (TI), repetition time (TR) and echo time (TE).

In magnetic resonance imaging, a standard pulse sequence used to produce T1-weighted images.See also: recovery
