Nuclear medicine extravasations and prolonged venous stasis may cause poor quality and quantification errors that can affect image interpretation and patient management. Radiopharmaceutical remaining near the administration site means that some portion of the radioactivity is not circulating as required for the prescribed uptake period. This case describes how detection of excess presence of Tc-MDP near the injection site enabled the technologist to apply mitigation tactics early in the uptake process. It also suggests that detecting an extravasation or stasis early in the injection process can be important for image interpretation and minimizing radiation dose to tissue.
核医学外渗和长时间静脉淤滞可能会导致图像质量不佳和定量误差，进而影响图像解读和患者管理。放射性药物残留在给药部位附近意味着部分放射性在规定的摄取期内未按要求循环。本病例描述了如何通过检测注射部位附近过量存在的锝-亚甲基二膦酸盐（Tc-MDP），使技术人员能够在摄取过程早期采取缓解措施。这也表明，在注射过程早期检测到外渗或淤滞对于图像解读和将组织辐射剂量降至最低可能很重要。
