Fat suppression is an MRI technique in which fat signal from adipose tissue is suppressed to better visualize uptake of contrast material by bodily tissues, reduce chemical shift artifact, and to characterize certain types of lesions such as adrenal gland tumors, bone marrow infiltration, fatty tumors, and steatosis by determining the fat content of the tissues.
[1] Due to short relaxation times, fat exhibits a strong signal in magnetic resonance imaging (MRI), easily discernible on scans.
Fat suppression can be achieved through various techniques as outlined below: [2][3] The choice of a specific fat suppression technique should be guided by several factors, including the intended purpose—whether it is for contrast enhancement or tissue characterization.
Considerations such as the quantity of fat in the tissue under examination, the magnetic field strength, and the homogeneity of the main magnetic field play crucial roles in the selection process.
