Feasibility of in vivo thyroid 131I monitoring with an imaging plate.
A new in vivo thyroid 131I monitoring method was devised by using an imaging plate (IP). A thyroid image obtained with a realistic neck-thyroid phantom showed a unique shape characteristic of the thyroid gland. A 131I thyroid imaging allows visual confirmation of thyroid accumulation of 131I. The detection limit of the IP system of 290 Bq was about 1/100 of the screening level of 30 kBq in cases of public emergencies. The IP system is applicable for thyroid 131I monitoring.
