<p>A method for identifying tumor cells exhibiting the Multidrug Resistance (MDR) characteristic utilizing a pair of radiolabeled compounds to form a difference image of the cells is provided. One of the radiolabeled compounds is a substrate for P-glycoprotein and the other is not. The radiolabeled compounds may be labeled with the same or different radioisotope, and the compounds may be introduced or administered sequentially or simultaneously to obtain the difference image in one or two imaging sessions, respectively.</p> |
