What does short tau inversion recovery signal mean in the navicular bone?

This talk will aim to look at what STIR signal means both from a magnetic resonance imaging (MRI) physics perspective as well as looking at its clinical implication with respect to the navicular bone. STIR stands for short tau inversion recovery and is a specific type of MRI sequence used to detect the presence of abnormal fluid signal within bone. MRI is the only imaging modality that can detect the abnormal presence of fluid within bone and the STIR sequence is fundamental in helping us make this diagnosis. Due to the properties of the STIR sequence it is specifically able to detect the presence of fluid within bone. This is in comparison with other sequences where it can be difficult to differentiate fluid from other bony pathologies, such as sclerosis. In addition to this, some sequences are insensitive to the presence of fluid ...
