Abstract

Histology on a core or open biopsy is considered the gold standard for the diagnosis of tumours. While the non-invasive technique of magnetic resonance imaging can direct some of the decision diagnostic making, it has limitations and disadvantages, that can be partly overcome with the use of in vivo magnetic resonance spectroscopy (MRS). In vivo MRS is able to provide a specific biochemical profile on tumour tissue, compared with normal tissue. The capability of this technique is demonstrated here by the long-term development of hepatocellular carcinoma in an animal model. It allows the observation of the biochemical changes that occur in tumour tissue during its progression from preneoplastic nodules to hepatocellular carcinoma. Specifically the changes in the lipid profiles of tumour tissue at various stages of development are observed with proton (1H) MRS. Significant increases occurred in the lipid acyl chain methylene and methyl hydrogens during the early developmental stages of hepatocarcinogenesis, whereas during later stages associated with tumour development there was a significant increase in the levels of olefinic acyl chain hydrogens from unsaturated lipids. It is anticipated that this model will precede the application of the same technology to the non-invasive diagnosis and grading of human hepatocellular carcinoma.
