Binh DD, et al. – This article enlightened the potential use of dual–energy computed tomography (DECT) for the functional assessment of the thyroid gland. The experts concluded that the negative correlation of ¹²³I uptake at 3 h with iodine concentration evaluated by DECT was better than that observed with simple CT value. These findings indicated that DECT probably had a potential role in the evaluation of iodine turnover in hyperthyroid patients.
