Biodistribution of ^99mTc-RRL in HepG2 xenograft-bearing mice.

<p>The ratio of T/NT of blood, liver, kidney and skeletal muscle showed better biodistribution of the probe (A). T/B and T/L ratio of experimental group were significant higher than that of blocking or control group. ‘*’ represented P<0.05. Comparison of %ID/g of interesting organs among experimental, blocking and control group at 6 h post injection was shown (B). Data were expressed as the mean value ± SD (n = 5). Higher uptake of kidneys and bladder caused by the probe clearance, yet higher stomach uptake was because of the uptake of free technetium-99 m.
