    “…RESULTS: Radiosynthesis resulted in 15–20% for iodo-bromo exchange and 50–60% yield for iodo-iodo exchange while in vitro experiments showed a pH-sensitive uptake for all tracers. Shelf-life stability and in vivo stability was excellent for all tracers. [(123)I]IPMM and [(123)I]IPM showed a moderately fast predominantly biliary clearance while a high retention was observed in blood. …”
