Nuclear Imaging of Glucose Metabolism: Beyond ¹⁸F-FDG

Figure 8

Radiation dosimetry and biodistribution of ^99mTc-EC-DG in patients with non-small-cell lung cancer. (a) Whole-body images of ^99mTc-EC-DG in a patient with NSCLC in the right upper lung (arrow), obtained after administration of 925 MBq (25 mCi). The images were acquired immediately and 2, 4, 6, and 24 h after injection. (b) CT attenuation-corrected SPECT transverse slices obtained after administration of 925 MBq (25 mCi) of ^99mTc-EC-DG in a patient with NSCLC in the medial posterior right upper lung (solid arrow). Uptake is also seen in the blood pool (great vessels; dashed arrows). The three images (left to right) are from the 2, 4, and 6 h SPECT scans, respectively.
