dc.description.abstractPURPOSE: To compare T2 relaxation times (T2) in the cingulate cortex, amygdaloid body, hippocampal body, and insular cortex between 1.5T and 3.0T MR imagers. MATERIALS AND METHODS: Twelve healthy volunteers underwent FLAIR and CPMG imaging perpendicular to the hippocampal body at both 3.0T and 1.5T. T2 was measured in the cingulate cortex, amygdaloid body, hippocampal body, and insular cortex. The T2 relaxation time ratios of the cingulate cortex, insular cortex, and amygdaloid body to the hippocampal body were compared between 1.5T and 3.0T. RESULTS: The mean T2 of the cingulate cortex, amygdaloid body, hippocampal body, and insular cortex at 1.5T were 109.5+/-3.1, 117.0+/-7.1, 114.7+/-2.4, and 111.3+/-2.4, respectively; 99.7+/-3.8, 100.7+/-4.3, 97.9+/-3.4, and 96.2+/-2.0, respectively, at 3.0T. Percentage changes of T2 in the cingulate cortex, insular cortex, amygdaloid body, and hippocampal body at 3.0T with respect to those at 1.5T were -8.9%, -13.5%, -14.6%, and -13.5%, respectively. The mean T2 ratios of the cingulate gyrus, insular cortex, and amygdaloid body to the hippocampal body at 1.5T and 3.0T were 0.96 and 1.02 (p=0.003); 1.02 and 1.03 (p>0.05); 0.97 and 0.98 (p>0.05), respectively. CONCLUSION: T2 decrease in the cingulate cortex was less than the amygdaloid body, insular cortex, and hippocampal body at 3.0T. The mean T2 ratio of the cingulate gyrus to the hippocampal body was significantly different between 1.5T and 3.0T-
