Copper dotatate Cu-64
Copper Cu 64 dotatate is a newly approved Cu labeled somatostatin analog and has several advantages over 68Ga-labeled somatostatin analogs for positron emission tomography (PET). Copper Cu 64 dotatate has a longer half-life and can be produced once a day as opposed to several times a day, and lower positron energy lending to improved spatial resolution. Further studies should be performed to compare the two tracers.   Further, PET using Copper Cu 64 dotatate has been found to perform better than the current gold standard of single-photon emission computed tomography (SPECT) using 111In-DTPA-octreotide. In a head-to-head trial, the former tracer detected twice as many lesions as the latter.
