A middle-aged woman underwent Tc-sestamibi parathyroid scintigraphy because of parathyroid disease, and a focal pulmonary uptake of Tc-sestamibi was incidentally found on both planar and SPECT/CT images without corresponding pulmonary abnormality on the CT images. After 10 days, a subsequent parathyroid scintigraphy revealed no pulmonary accumulation. Therefore, the pulmonary intense Tc-sestamibi focus that once appeared in the first scan might be an artifact of iatrogenic microembolism from injection site.
一位中年女性因甲状旁腺疾病接受了 Tc-sestamibi 甲状旁腺闪烁显像，在平面和 SPECT/CT 图像上均意外发现 Tc-sestamibi 肺摄取，而 CT 图像上无相应的肺部异常。10 天后，随后进行的甲状旁腺闪烁显像显示无肺部聚集。因此，第一次扫描中出现的肺部强烈的 Tc-sestamibi 焦点可能是注射部位医源性微栓塞的伪影。
