Design outcomes

Primary

MeasureTime frame
Primary end point(s): I124 test the efficacy of PET / CT in the detection of recurrence.;Main Objective: 124i and [18F] FDG PET / CT identification of repetitive lesions responsible for raising the Tg values and / or AbTg in patients undergoing total thyroidectomy and subsequent radioiodine therapy with negative ultrasound of the neck;Secondary Objective: To correlate the different types of uptakes, 124i or [18F] FDG, with the different oncogenic profiles shown in primary tumors and, where possible, with the profiles of the oncogenic metastases.
