Dotatate gallium Ga-68
Dotatate gallium (Ga-68) is a somatostatin-2 receptor analog which is radiolabeled with gallium 68 as a positron-emitting radioisotope. Ga-68 dotatate has a high affinity for somatostatin-2 receptor and it is rapidly excreted from the nontarget sites which gives it an ideal candidate for imaging neuroendocrine tumors. Dotatate gallium (Ga-68) explotes its ability to detect somatostatin receptor scintigraphy and this characteristic tends to change with tumor grade which gives Ga-68 dotate a high diagnostic value. Dotatate gallium 68 was developed by Advanced Accelerator Applications USA, Inc. and FDA approved in June 1, 2016.
