Abstract:
The radioactive iodine uptake(RAIU) has great value in determining the 131I treatment dosage of patients suffered from hyperthyroidism and judging thyroid function. Many factors which could interfere the results of RAIU were as follows: instrumental factors, thyroid radioactivity counts measurement, counts of a calibrated standard in a neck phantom and counts of room background, iodinated drugs and food, anti-thyroid medication, among other causes, have shown to induce varying degrees of errors in RAIU measurements. Irregular measurements which may interfere with radioactive iodine uptake are commonly seen in clinical practice, yet its actual influence has not been reported. Optimization, regularization and quality control of the radioiodine uptake measurement are essentials for clinical routine practice to guarantee appropriate values for clinical hyperthyroidism diagnosis and treatment. All the above factors affecting the measurement of thyroid function instrument for radioactive iodine uptake are analyzed and then put forward the corresponding solutions.
