the new agent , [ 125i ] -19 , showed high myocardial uptake ( 5 min , 4.89 % dose/g ; 30 min , 3.32 % dose/g ) , good heart/blood ( h/b ) ratios ( 5 min , 5.4/1 ; 30 min , 4.3/1 ) , and significantly greater myocardial retention in fasted rats than the corresponding straight-chain analogue 19- [ 125i ] -iodo-18-nonadecenoic acid ( 5 min , 3.52 % dose/g , h/b = 4.8/1 ; 30 min , 1.19 % dose/g , h/b = 1.6/1 ) .
