^99mTc-Radiolabeled TPGS Nanomicelles Outperform ^99mTc-Sestamibi as Breast Cancer Imaging Agent

Figure 3

Gamma camera imaging of ^99mTc-sestamibi (15 min after injection) and ^99mTc-radiolabeled TPGS micelles (12 h after injection) in a breast cancer animal model developed with NMU carcinogen in Sprague-Dawley rats. Each animal was scanned with both radioactive probes, and representative images from (a) rat#1 and (b) rat#2 are shown. Yellow arrow indicates palpable tumoral site; A, B, and C represent tumor identification on each rat.
