Automated vessel exclusion technique for quantitative assessment of hepatic iron overload by R2* ‐MRI

Extraction of liver parenchyma is an important step in the evaluation of R2* ‐based hepatic iron content (HIC). Traditionally, this is performed by radiologists via whole‐liver contouring and T2* ‐thresholding to exclude hepatic vessels. However, the vessel exclusion process is iterative, time‐consuming, and susceptible to interreviewer variability.
