Short tau inversion recovery (STIR), also known as short TI inversion recovery, is a fat suppression technique with an inversion time TI = ln(2)·T1fat, where the signal of fat is zero. This equates to approximately 140 ms at 1.5 T.
What is MRI stir?
STIR (Short Tau Inversion Recovery) images are highly water-sensitive and the timing of the pulse sequence used acts to suppress signal coming from fatty tissues – so ONLY WATER is bright. A combination of standard T1 images and STIR images can be compared to determine the amount of fat or water within a body part.

What is stir signal abnormality?
When an abnormally bright, diffuse MR signal intensity on STIR imaging is seen more than 6 months after an original injury, such abnormal signal intensity is likely to represent new injury.
