Stir does not specifically suppress fat Heterogeneous bone marrow signal is a common but challenging mri finding Likewise, suppression proteinaceous materials and other short t1 tissues may occur.

Diffuse t1 vertebral bone marrow signal loss is associated with replacement of fatty bone marrow by edema or cellular tissue.
Stir (short tau inversion recovery) imaging is a specialized mri technique designed to enhance the visibility of abnormalities in tissues by suppressing the signal from fat.
Discover the root causes behind abnormal bone marrow signals on mri scans and learn about potential treatments. Stir is particularly useful in musculoskeletal imaging to detect edema and lesions in tissues with high fat content. Stir sequences are primarily used for fat suppression, which is crucial for improving the visibility of lesions and abnormalities in mri scans The principle behind fat suppression in stir imaging lies in the differences in the relaxation times of various tissues.
Low t1 bone lesions or t1 hypointense bone lesions are radiological terms to categorise bone lesions according to their visually perceived low signal on t1 weighted images.
