Ga 68 Dotatate Protocol. 3 Ga-68 DOTATATE targets mainly somatostatin receptor subtype 2 SSTR2 and provides superior image quality lower radiation dosimetry and greater patient convenience compared to In-111 octreotide. With the results of the present study and the increasing availability and use of DOTA analogs in the therapy of neuroendocrine tumors we expect that 68Ga-DOTATATE PETCT will become the preferred functional imaging mod. Measured human dosimetry of the 68 Ga-labeled synthetic somatostatin analog 68 Ga-DOTATATE has not been reported in the peer-reviewed literature. Use waterproof gloves effective radiation shielding and appropriate safety measures when preparing and handling Ga 68 dotatate injection.
Routine protocol is water oral contrast during the uptake phase and for 1 hour prior when possible If positive oral contrast is requested by the radiologist. -Positivity of Ga-68-DOTATATE PET scan defined as having at least one lesion that is greater than or equal to 10 mm in diameter with uptake that is higher than or equal to liver and is qualitatively higher and distinguishable from background activity. Warnings and Precautions 51. With the results of the present study and the increasing availability and use of DOTA analogs in the therapy of neuroendocrine tumors we expect that 68Ga-DOTATATE PETCT will become the preferred functional imaging mod. Preferably with Ga-68 DOTATATE but In-111 Octreoscan is acceptable. Results support the routine use of Ga-68 Dotatate PETCT in the care of patients with advanced and early stage NETS.
68Ga has a short half-life of 68 minutes compared with 28 days for 111In resulting in a lower radiation dose to the pa-tient with an effective dose of.
Introduction This protocol MUST be used when performing 68-Ga Dotatate PET-CT imaging. Gallium-68 radiolabeled-DOTATATE imaging which is a sensitive method of detecting staging characterizing the disease and monitoring the effects of therapy 2. Scope The procedures laid out in this protocol apply to the radiographer technologists in PET-CT and should be carried out when performing a 68-Ga Dotatate PET-CT. Gallium 68 68Ga is. 68Ga-Dotatate PET-CT Scanning Protocol UK 1. Scope The procedures laid out in this protocol apply to the radiographer technologists in PET-CT and MUST be carried out when performing a 68-Ga PSMA PET-CT.
