Technetium-99m-sestamibi uptake by human benign and malignant breast tumor cells: correlation with mdr gene expression.

Abstract

Technetium-99m-sestamibi uptake by these breast tumor cells is energy-dependent but not specific. These data suggest that 99mTc-sestamibi imaging may be used as a noninvasive technique to diagnose the presence of MDR in breast tumors in vivo.
