FAPI PET/CT provides higher uptake and better target to back ground in recurrent and metastatic tumors of patients with Iodine refractory papillary thyroid cancer compared with FDG PET CT.

Purpose: The role of fibroblast activation protein inhibitor (FAPI) PET CT scan is not well documented in papillary thyroid cancer (PTC) patients. Patients with radioiodine refractory PTC and high thyroglobulin levels need PET/CT scan which is generally done by 18F FDG. In the current study, the diagnostic performance of 68Ga FAPI and FDG PET/CT scans were compared head to head in patients with radioiodine refractory PTC.

Pattern of tobacco use among the Iranian adult population: results of the national Survey of Risk Factors of Non-Communicable Diseases (SuRFNCD-2007).

Background: Previous studies report on smoking in Iran but recent national data on tobacco use (including cigarette, water-pipe and pipe) have not been reported.

Methods: In 2007, 5287 Iranians aged 15-64 years were sampled from all provinces as part of a national cross-sectional survey of non-communicable disease (NCD) risk factors. Data were collected using the standardised stepwise protocol for NCD risk factor surveillance of the World Health Organization.
