Table 3 Comparison between hepatic steatosis staging by histology and 1H MRS

From: Quantitative MDCT and MRI assessment of hepatic steatosis in genotype 4 chronic hepatitis C patients with fibrosis

  1. aCutoff values for hepatic steatosis were 5, 33, and 66% of involved hepatocytes for histology and 4.95, 8.4, and 20.3% of MRS signal for 1H MRS method. In 74% of patients an agreement between
  2. histological and 1H MRS steatosis assessment was achieved
