Liver diagnosis breakthrough with Mayo Clinic MRI development
...ionally, liver fibrosis is usually diagnosed using needle biopsies, which can involve complications and may be inaccurate due to sampling errors. The new technology promises to provide an accurate, painless, and lower risk alternative to liver biopsy and may have implications for diagnosing cancer.
