WebOn the T2-W TSE images, this signal difference was 4-79% (mean 36%) and on the T1-W SE images 6-77% (mean 37%). Conclusion. The TIRM sequence is highly sensitive for detecting bone marrow oedema in the very early stage of acute osteomyelitis in children. MRI utilising the TIRM sequence allowed for an early diagnosis. WebAs the spins relax back to their equilibrium configuration the signal for each spin group will evolve from a negative signal which is zero (null point) to a positive signal. This rate is determined by the T1 of the spin group. Since at 1.5 T, T1 fat= 260 ms and for most other tissues T1 > 500 ms.
