This framework was then applied to two sample proton-density weighted MRI applications that demonstrated estimation of minimum field strength requirements: real-time upper airway imaging and liver proton-density fat fraction measurement. The phantom experiment showed good agreement between simulated and ...
We aimed to evaluate the feasibility of quantification of liver, pancreas, spleen, vertebral bone marrow, and renal cortex R2* and magnetic resonance imaging-proton density fat fraction (MRI-PDFF) and to evaluate the correlations among them in patients with transfusion-related iron overload.A tot...
NAFLD prevalence, defined by magnetic resonance imaging–proton density fat fraction ≥5%, was 66%. Eighty﹐ne percent of those with baseline liver fat (BL) ≥5% had improvement in liver fat content, and NAFLD resolved in 33% of ... S Albhaisi,K Kim,J Baker,... - 《Hepatology Communic...
Our research aims to validate MRI Proton Density Fat Fraction (MRI-PDFF) utility, compared to liver biopsy, in grading hepatic steatosis in MASLD. Methods A systematic search was conducted across Embase, PubMed/Medline, Scopus, and Web of Science until January 13, 2024, selecting studies that...
