MRI Sequences | Advantages

STIR – Short Tau Inversion Recovery

The STIR sequence, designed to suppress signal from fat, also enhances the signal from tissue with long T1 and T2 relaxation times, such as neoplastic and inflammatory tissue.

Golfeiri et al 1990

TIRM – Turbo Inversion Recovery Magnitude

The TIRM sequence is highly sensitive for detecting bone marrow oedema in the very early stage of acute osteomyelitis in children.

Hauer et al 1998


  • Fat appears bright
  • Water has low signal and appears dark
  • T1 images provide best contrast post gadolinium
