Usefulness of fat-suppression magnetic resonance imaging for oral and maxillofacial lesions. Fat suppression techniques in MRI: an update. De Kerviler E, Leroy-Willig A, CléMent O et-al. Radiographics (full text) - Pubmed citation Fat suppression in MR imaging: techniques and pitfalls. Selection of a fat suppression technique should depend on the purpose of the fat suppression (contrast enhancement vs tissue characterization) and the amount of fat in the tissue being studied, the field strength of the magnet and the homogeneity of the main magnetic field. hybrid techniques combining several of these fat suppression techniques such as SPIR (spectral presaturation with inversion recovery).short T1 relaxation time by means of inversion recovery sequences ( STIR technique).phase contrast techniques (by same mechanism as black boundary or india ink artifacts).
Lastly, a contrast enhancing tumor may be hidden by the surrounding fat. The high signal can also mask subtle contrast difference in non-fatty tissue by filling the dynamic range of the receiver with mostly fat signal. In addition, the high signal due to fat may be responsible for artifacts such as ghosting and chemical shift. However, small amounts of lipids are more difficult to detect on conventional MRI. This high signal, easily recognized on MRI, may be useful to characterize a lesion 2.
Fat suppression is commonly used in magnetic resonance (MR) imaging to suppress the signal from adipose tissue or detect adipose tissue 1. It can be applied to both T1 and T2 weighted sequences.ĭue to short relaxation times, fat has a high signal on magnetic resonance images (MRI).
