We have reviewed our experience over the past 5 years of 32 thyroid scans in Hashimoto's thyroiditis. A wide variety of images were obtained, the most common finding being that of an enlarged gland with diffusely increased tracer uptake, a pattern identical to that found in Graves' disease (eight patients). Of the remainder, four scans were normal, four showed an enlarged gland with normal tracer uptake, five a multinodular gland with normal tracer uptake, five a multinodular gland with high tracer uptake, five a single non-functioning nodule and in one patient there was low tracer uptake by the gland. It is apparent that the thyroid scan in Hashimoto's thyroiditis can mimic a wide range of thyroid disorders. Thus, taken in isolation, the scan findings can be misleading and should be evaluated in conjunction with current biochemistry.
我们回顾了过去5年中对32例桥本甲状腺炎患者进行甲状腺扫描的经验。获得了各种各样的图像，最常见的发现是甲状腺肿大且放射性示踪剂摄取弥漫性增加，这一表现与格雷夫斯病相同（8例患者）。其余患者中，4次扫描结果正常，4次显示甲状腺肿大但放射性示踪剂摄取正常，5次显示多结节性甲状腺且放射性示踪剂摄取正常，5次显示多结节性甲状腺且放射性示踪剂摄取高，5次显示单个无功能结节，1例患者甲状腺放射性示踪剂摄取低。显然，桥本甲状腺炎的甲状腺扫描可模拟多种甲状腺疾病。因此，单独来看，扫描结果可能会产生误导，应结合当前的生化检查进行评估。
