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 1 and in the assessment of head and neck tumors 2.
