Liver biopsy is the gold standard to examine the liver for iron deposits and histology. However, liver biopsy is invasive and involves a risk of bleeding and pain. Biopsy may also miss significant pathology if the small biopsy specimen is taken from an uninvolved part of the liver. Non-invasive techniques such as MRI are now used to evaluate the liver iron content. MRI can visualize the whole liver and measure liver iron content. MRI, however, will not detect liver scarring.
