Integrin antagonist complex (IAC), a novel αvβ3 integrin antagonist peptidomimetic, has emerged as a promising agent for molecular imaging of tumor angiogenesis. This study evaluates the biodistribution and clinical efficacy of [Ga]Ga-DOTAGA-IAC PET/CT in detecting radioiodine-refractory differentiated thyroid carcinoma (RAIR-DTC), comparing its diagnostic performance with [F]F-FDG PET/CT. In this prospective pilot study, RAIR-DTC patients underwent whole-body imaging with [F] F-FDG PET/CT, followed by [Ga]Ga-DOTAGA-IAC PET/CT.

Differentiated thyroid cancer (DTC) generally has a favorable prognosis, and radioactive iodine (RAI) therapy is typically used for metastatic DTC that continues to progress and poses life-threatening risks. However, resistance to RAI in metastatic DTC significantly impairs treatment effectiveness. This study aims to identify potential compounds that may influence RAI efficacy.

In China, due to the risks of hypothyroidism after radioiodine treatment, radioiodine is not commonly used as a first-line treatment. In this study, factors influencing the development of hypothyroidism after I therapy for Graves' hyperthyroidism were evaluated. This was a retrospective study with a 12-month follow-up.

Department of Nuclear Medicine, Hospital 108, Hanoi, Vietnam.
Objective: Identifying prognostic markers for clinical outcomes is crucial in selecting appropriate treatment options for patients with radioiodine-refractory (RAI-R) differentiated thyroid carcinoma (DTC). The aim of this study was to investigate the prognostic value of clinico-pathological features and semiquantitative [F]FDG PET/CT metabolic parameters in predicting progression-free survival (PFS) in DTC patients with RAI-R.
Patients And Methods: This prospective cohort study included 110 consecutive RAI-R DTC patients who were referred for [F]FDG PET/CT imaging.
Iodine transfer to dairy cow's milk: A revised biokinetic model.

A new biokinetic model for iodine in dairy cows was developed utilizing data from a 4 × 4 factorial feeding experiment with rumen-cannulated cows that were fed rapeseed cake containing substances known to influence iodine metabolism, and soybean meal without such effects. I was administered both intravenously and intra-ruminally to document metabolism pathways. The new model included compartments such as saliva and thyroid gland, often ignored in other models, and in contrast to previously available biokinetic models, it fitted well to our experimental data.
