Variability of magnetic resonance parameters in pituitary adenomas at low temperature.
Temperature dependent spin-lattice relaxation time, T1, measurements were carried out on surgically removed pituitary adenoma tissues at low temperature. Differences were found between samples; the temperature dependence of T1 showed a broad minimum below freezing. The measured data were fitted by theoretical lines to determine various parameters such as activation energy, correlation time and intensity.
