The aim of this study was to investigate thyroid T1 value in patients with hypothyroidism (HT). 21 untreated females with clinical hypothyroidism (HT) and 21 healthy control females underwent the thyroid T1 maps with Modified Look-Locker Inversion Recovery technique at 3T MR (Siemens TimTrio). All patients received levothyroxine therapy and were followed after 6 months. The results showed thyroid T1 value at 3T was technically feasible and pretreatment thyroid T1 value increase in HT patientscompared with normal woman. After treatment, thyroid T1 value decreased. These suggest T1 mapping may improve disease detection and quantitatively monitor thyroid disease.
