T2 TSE / T2 FSE Fat Saturated MRI Sequence
MRI image appearance
The easiest way to identify T2-weighted fat-saturated images is to observe the presence of adipose tissues in the body, such as subcutaneous fat and fat in the bone marrow. Areas containing adipose tissues appear dark on T2-weighted fat-saturated images. All other characteristics of the T2-weighted fat-saturated images remain the same as those in T2-weighted images.
Tissues and their T2 fat saturated image appearance
Bone marrow: – dark
Muscles- dark gray
Fat – dark
White matter – dark gray
Moving blood- dark
Gray matter – gray
Fluids – bright
Bone – dark
Air – dark
Use
- Useful for chest imaging
- Useful for pancreas imaging
- Useful for kidney imaging
- Useful for abdominal imaging
- Useful for spine imaging
- Useful for pelvic imaging
- Useful for anterior neck, orbits and face imaging
- Useful for any musculoskeletal imaging
- Useful for extremity imaging
Pathological appearance
Pathologies with adipose tissue content will appear dark on T2-weighted fat-saturated images (e.g. lipoma). Due to the added fat suppression, pathological processes are usually very bright on T2-weighted fat-saturated images.
* Most of the post contrast examinations use fat saturated post contrast T1 sequences except brain imaging.*
