There are different classes of glucose transporters for two forms of glucose transport. SGLT1 and SGLT2 are sodium glucose cotransporters involved in secondary active transport, and GLUT1 to GLUT13 are facilitated glucose transporters (<a class="bibr" href="#DG99mTc.REF.3" rid="DG99mTc.REF.3">3</a>). They are similar in that they have a polypeptide chain of 500 amino acids. After glucose enters a living cell, phosphorylation catalyzed by hexokinase transforms the molecule to glucose-6-phosphate (G-6-P). There are four hexokinase isoforms (HKI to HKIV) that exist in mammalian tissues (<a class="bibr" href="#DG99mTc.REF.4" rid="DG99mTc.REF.4">4</a>). The G-6-P isomerase then converts G-6-P into fructose-6-phosphate (F-6-P) by rearranging the carbonyl group from the C-1 to the C-2 position in the ring structure to enter further metabolic pathways. Cancer cells are known to have accelerated metabolism, high glucose consumption, and increased glucose uptake (<a class="bibr" href="#DG99mTc.REF.5" rid="DG99mTc.REF.5">5</a>). In humans, high levels of GLUT expression in tumors have been associated with poor survival. Increased HK activities have also been associated with metastatic disease.</p><p>Molecular imaging with glucose analogs is a useful tool in the detection, staging, and therapy response monitoring of various malignant neoplasms (<a class="bibr" href="#DG99mTc.REF.6" rid="DG99mTc.REF.6">6</a>, <a class="bibr" href="#DG99mTc.REF.7" rid="DG99mTc.REF.7">7</a>). <a href="/books/n/micad/FDG/?report=reader">2-[<sup>18</sup>F]Fluoro-2-deoxy-2-<span class="small-caps">d</span>-glucose ([<sup>18</sup>F]FDG)</a> was the first successful radiolabeled glucose analog developed for clinical positron emission tomography (PET) applications (<a class="bibr" href="#DG99mTc.REF.8" rid="DG99mTc.REF.8">8</a>). [<sup>18</sup>F]FDG, like glucose, is transported into cells by glucose transporters and is a substrate for hexokinase. However, it is converted to [<sup>18</sup>F]FDG-6-phosphate ([<sup>18</sup>F]FDG-6-P), which cannot be further metabolized. [<sup>18</sup>F]FDG-6-P is not a substrate for the G-6-P isomerase and therefore is metabolically trapped in the cell. The trapping of [<sup>18</sup>F]FDG-6-P within cells and tissues allows <i>in vivo</i> PET imaging of glucose utilization rates in normal and pathologic tissues. Because of the short <i>t</i><sub>½</sub> of <sup>18</sup>F and the requirement of cyclotron production, it is desirable to develop a gamma-emitter for SPECT imaging (<a class="bibr" href="#DG99mTc.REF.9" rid="DG99mTc.REF.9">9</a>).
