Indium-111 The indium-111 pentetreotide radiopharmaceutical is prepared from a kit in a radiopharmacy. Pentetreotide is a DTPA conjugate of<unk> . Approximately 200 megabecquerels (MBq) of indium-111 is injected intravenously. Imaging takes place 24 hours after injection, but may also be carried out at 4 and 48 hours. Technetium-99m The 99mTc product is supplied as a kit with two vials, one containing the chelating agent ethylenediaminediacetic acid (EDDA) and the other the HYNIC-Tyr3-octreotide chelator and somatostatin analog. Approxiamtely 400-700 MBq may be administered, with imaging at 2, 4, and occasionally 24 hours post administration. 99mTc based<unk>  imaging shows slightly higher sensitivity than 111In.
