FIGURE 1. Patient 1, 73-y-old man with 2.8 x 2.8 cm lung adenocarcinoma. (A) CT scan shows nodule in right lung. (B) Early ^99mTc-MIBI SPECT scan (left) shows intense uptake (arrow) of ^99mTc-MIBI in tumor (L/Ne = 3.81). Delayed scan (right) shows faint ^99mTc-MIBI uptake in tumor (L/Nd = 1.00), suggesting rapid washout of ^99mTc-MIBI from tumor (L/Nwr = 73.8%). Immunohistochemistry (x200) reveals strong Pgp expression (C), strong MRP expression (D), and weak LRP expression (E) in corresponding tumor tissue.
