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 (IR)
a magnetic resonance pulse sequence designed to emphasize T1 differences.
inversion recoveryAn 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.
