Abstract

The objective of this work was to set up a method to formulate a complex for the assessment of myocardial infarction in vivo. Labetalol was successfully labeled with ^99mTc using SnCl₂·2H₂O as reducing agent. Various reaction parameters were investigated to optimize the labeling yield. The labeled complex was stable for up to 24 h. The heart uptake was 35.5 % ID/Organ at 5 min post-injection, while the clearance pathways from the body behave via both the hepatobiliary and renal routes.
