| Abstract: | Localization of 99mTc-MDP in lymph nodes was apparent on the three-hour bone-scan image in seven dogs. In six dogs injection or leakage of the radiopharmaceutical into the perivascular tissues was associated with subsequent uptake in an ipsilateral lymph node. In the remaining dog, 99mTc-MDP localized in a lymph node infiltrated by metastatic osteosarcoma. This aided staging of the tumor. Possible mechanisms of 99mTc-MDP localization in soft tissues are briefly reviewed. |
