Abstract
During sequential salivary gland scintigraphy with 99mTc-pertechnetate, circumscript "cold" areas with less than background activity are sometimes seen in the region of the oral cavity. This phenomenon is due to the presence of extensive dental restorations and should not be misinterpreted in terms of deficient 99mTc-pertechnetate uptake in the minor salivary glands of the oral cavity.
摘要
在使用高锝[99mTc]酸盐进行唾液腺连续闪烁扫描时，口腔区域有时会出现放射性低于本底的局限性“冷”区。这种现象是由于存在大量牙齿修复体所致，不应将其误解为口腔小唾液腺摄取高锝[99mTc]酸盐不足。
