Multiecho Dixon fat-water separation in cardiac MRI provides advantages over conventional fat-saturation techniques, including fewer artifacts and improved contrast of microscopic fat.
Does multiecho Dixon fat-water separation offer advantages over conventional fat-saturation techniques in cardiac MRI?
Multiecho Dixon fat-water separation is a valuable technique in cardiac MRI for characterizing masses, evaluating lipomatous infiltration, and diagnosing pericarditis, offering several advantages over conventional fat-saturation.
OBJECTIVE: The purpose of this pictorial essay is to explore the advantages of multiecho Dixon fat-water separation techniques in cardiac MRI. The clinical indications, potential artifacts, and imaging findings with this technique are reviewed. CONCLUSION: Multiecho Dixon fat-water separation can be used to help characterize cardiac masses, evaluate for myocardial lipomatous infiltration, and diagnose pericarditis. Advantages over conventional fat-saturation techniques include fewer artifacts from background inhomogeneity, improved contrast of microscopic fat, and capability for use in combination with cine and contrast-enhanced imaging.
Farrelly et al. (Wed,) conducted a review in Cardiac masses, myocardial lipomatous infiltration, pericarditis. Multiecho Dixon fat-water separation vs. Conventional fat-saturation techniques was evaluated. Multiecho Dixon fat-water separation in cardiac MRI provides advantages over conventional fat-saturation techniques, including fewer artifacts and improved contrast of microscopic fat.
