The effects of neck diameter, thyroid volume, and prethyroid tissue thickness on a count-activity conversion coefficient and the detection limit of a thyroid 131I monitoring system with an imaging plate (IP) were estimated by using an anthropomorphic thyroid-neck phantom. The conversion coefficient and detection limit of the IP system was approximately constant for normal Japanese adults regardless of their neck diameters, thyroid volumes, and prethyroid tissue thicknesses. The IP system is a new option for thyroid 131I monitoring.
使用拟人化甲状腺颈部模型,评估了颈部直径、甲状腺体积和甲状腺前组织厚度对成像板(IP)甲状腺131I监测系统的计数-活度转换系数和探测限的影响。对于正常日本成年人,IP系统的转换系数和探测限大致恒定,与他们的颈部直径、甲状腺体积和甲状腺前组织厚度无关。IP系统是甲状腺131I监测的一种新选择。
