Abstract

Pharmacokinetics and mediastinal node uptake of [111In]-avidin and [99mTc]-biotin-liposomes following either intrapleural (pleural) or intraperitoneal (ip) injection were determined using scintigraphic imaging. Biodistribution results of [111In]-avidin at 44 h showed 3.3% uptake in mediastinal nodes by pleural injection vs 1.3% with ip injection. Mediastinal node accumulation with [99mTc]-biotin-liposomes was not different between injections (0.6% ip vs 0.5% pleural). This study demonstrates the potential of the pleural route as a technique for mediastinal node targeting using the avidin/biotin-liposome system.
