Abstract
Twenty-one human hepatic liver biopsy samples were evaluated by nuclear magnetic resonance spectroscopy. This spectroscopy was performed by obtaining multiple and not single T2 values (T2-long and T2-short). Neoplastic tissue had greater T2-long and T2-short values than diffuse liver disease. The T2-short correlated, r = 0.947 (p less than 0.01), with the percentage of cancer cellularity within the tissue specimens. There was no correlation between the multiple T2 values and the degree of fibrosis and inflammation. Minimal correlation was noted between the T2-long and percentage of fat within the diffuse disease (cirrhotic) specimens, r = 0.636 (p less than 0.05). The possible reasons for the above findings are discussed.
