The receiver operating characteristic curve analysis demonstrated an area under the curve of 0.795 for GGT, 0.731 for AST and 0.709 for ALT. The optimal cut-off level of GGT as a marker for alcohol-associated ONFH was 36.5units/L, with a sensitivity of 76% and specificity of 80%, and it was found to be the best marker among the other examined laboratory markers. Serum GGT level is a useful laboratory marker with moderate accuracy that indicates habitual drinking in patients with alcohol-associated ONFH.

To use proton magnetic resonance spectroscopy (1HMRS) and diffusion weighted imaging (DWI) to identify ethanol in the brain directly after consumption, and examine changes in brain metabolite levels and brain microstructure relative to the duration of time following exposure to alcohol. The study involved 44 male volunteers (18-55years). All brain changes were assessed in the frontal lobes, occipital lobes, basal ganglia and cerebellum, however the detailed analyses focused on the frontal lobes. All participants were examined four times, i.e. before and 0.5-hour, 1hour and 2hours after consumption of 150mL pure vodka (60g of ethanol). The highest ethanol levels were identified between 0.5 and 1hour following alcohol intake. There were significant increases in the concentrations of lipids and lactates approximately one hour after alcohol consumption, and the concentration levels were found to normalise during the following two hours. Some statistically insignificant trends of changes were found for tCr, tCho, mI, GABA, Glc, Glx and tNAA. For the DWI and ADC (Apparent Diffusion Coefficient of water) values, the findings showed statistically insignificant decrease and increas
