1 The effect of P-glycoprotein function inhibition with cyclosporine A on the biodistribution of Tc-99m sestamibi. Technetium Tc 99m Sestamibi ATP binding cassette subfamily B member 1 Homo sapiens
2 Tc-99m sestamibi is a substrate for P-glycoprotein. Technetium Tc 99m Sestamibi ATP binding cassette subfamily B member 1 Homo sapiens
3 CONCLUSIONS: With a limited number of patients, this study suggests that Tc-99m sestamibi excretion from the liver is mediated by P-glycoprotein, and inhibition of P-glycoprotein transport not only delays liver excretion but also increases the liver uptake of Tc-99m sestamibi. Technetium Tc 99m Sestamibi ATP binding cassette subfamily B member 1 Homo sapiens
4 CONCLUSIONS: With a limited number of patients, this study suggests that Tc-99m sestamibi excretion from the liver is mediated by P-glycoprotein, and inhibition of P-glycoprotein transport not only delays liver excretion but also increases the liver uptake of Tc-99m sestamibi. Technetium Tc 99m Sestamibi ATP binding cassette subfamily B member 1 Homo sapiens
5 CONCLUSIONS: With a limited number of patients, this study suggests that Tc-99m sestamibi excretion from the liver is mediated by P-glycoprotein, and inhibition of P-glycoprotein transport not only delays liver excretion but also increases the liver uptake of Tc-99m sestamibi. Technetium Tc 99m Sestamibi ATP binding cassette subfamily B member 1 Homo sapiens
6 Because this observation deserves further investigation, the inhibition of P-glycoprotein function with nontoxic multidrug-resistance reversing agents may be used as an intervention to increase the tumor uptake of Tc-99m sestamibi and to increase the sensitivity of Tc-99m sestamibi tumor imaging. Technetium Tc 99m Sestamibi ATP binding cassette subfamily B member 1 Homo sapiens
