ABSTRACT
OBJECTIVE: To define the role of liver magnetic resonance (MR) spectroscopy in the evaluation of therapy for fatty hepatosis. MATERIAL AND METHODS: Spectra were studied in 49 patients (30 men and 19 women) whose mean age was 54+/-11 years. A study group consisted: 1) healthy volunteers (n = 10) and 2) patients with fatty hepatosis (n = 39) identified by clinical data. The patient group had two points: before and 6 months after treatment with Eslidin (based on polyunsaturated fatty acids). The lipid-to-water content ratio in the liver parenchyma was calculated for each patient. If its value was over 6.5%, the diagnosis of fatty hepatosis was considered verified. RESULTS: The findings showed that the ratio was not more than 3.2% in the group of healthy volunteers, which completely excluded hepatic fatty infiltration. In the patient group, the ratio was 15, 10, and 8.5% in 15, 20, and 4 cases, respectively. Reexamination revealed a reduction in fat concentrations to normal values (56,4%) in 22 patients and a more than twice (31%) decrease in 12 patients. No reduction in fat content was found in 5 (12,8%) patients. CONCLUSION: Proton MR spectroscopy is a reproducible procedure that may be used to evaluate the efficiency of treatment for fatty hepatosis. H1-spectroscopy can be used to evaluate the efficacy of some drugs for the treatment of this pathology.
