TīmeklisBackground. Radioactive iodine (RAI) uptake and scan is a direct, noninvasive test used to assess the function of the thyroid gland. RAI uptake and scan is frequently interchangeable with “RAI scan” or “RAI uptake” in clinical practice. However, the RAI test involves two separate phases including the uptake and the scan. Tīmeklis2024. gada 16. marts · A slight radioiodine uptake in a small thyroid remnant was noted, while an intense radioiodine uptake was detected in the lower lobe of the right lung, corresponding to a sub-pleural mass due to the confluence of nodular lesions with fibrotic streaks and traction bronchiectasis.
