PG - 433-42 AB - The ultrasmall superparamagnetic iron oxide colloid BMS 180549 can be found lymph nodes by either subcutaneous (SC) or intravenous (IV) injection. With an SC injection in the front extremities, the axillary and brachial nodes attain the highest accumulations of the agent. With an SC injection in the rear extremities, the popliteal, iliac, and axillary nodes attain highest accumulations of the agent. With IV injection of the agent, the iliac, mediastinal and mesenteric nodes attain highest accumulations of the agent. Though the spleen is not involved with the drainage of the interstitial space near the site of SC injections, the mobility of BMS 180549 from such injection sites increases splenic relaxation rates. Based on a knowledge of the lymphatic system, a route of administration of BMS 180549 can be chosen to maximize the delivery of the agent to specific lymph nodes.
