turbo Inversion Recovery Magnitude

Turbo inversion recovery magnitude (TIRM) is an inversion recovery MRI pulse sequence that displays the magnitude of a turbo/fast spin echo, without regard for the phase/polarity of the longitudinal magnetization. This method of image reconstruction is the dominant form of inversion recovery used and is contrasted to phase-sensitive inversion recovery (PSIR). The use of magnitude reconstruction allows selective nulling (making certain materials appear dark): inversion time can be set short for fat suppression (STIR) or long for fluid attenuation (FLAIR).

It has been shown to be superior in the assessment of osteomyelitis in bone and in the assessment of head and neck tumors .
