FIG 1. Left, Coronal view T2-weighted image of a control volunteer, obtained at the level of the body of the hippocampus. Region of interest is positioned in the left hippocampus. Right, Display of the relaxation curve and the calculated theoretical exponential curve. The relaxation curve of the tissue very closely matched the calculated theoretical exponential curve. T2 relaxation time measured by using both acquisition and measurement techniques correlated very closely.
