Hepatic iron content (HIC) quantification via transverse relaxation rate (R2*)‐MRI using multi‐gradient echo (mGRE) imaging is compromised toward high HIC or at higher fields due to the rapid signal decay.… Click to show full abstract

Hepatic iron content (HIC) quantification via transverse relaxation rate (R2*)‐MRI using multi‐gradient echo (mGRE) imaging is compromised toward high HIC or at higher fields due to the rapid signal decay. Our study aims at presenting an optimized 2D ultrashort echo time (UTE) sequence for R2* quantification to overcome these limitations.
