简要总结
The small insulinoma can not be detected by the CT or MRI. We use 68Ga-NOTA-exendin-4 positron emission tomography/computed tomography (PET/CT) to detect the insulinoma for the patient diagnosed with endogenous hyperinsulinemic hypoglycaemia. And the diagnostic value will be performed. A single dose of 37-111 Mega-Becquerel (MBq) 68Ga-NOTA-exendin-4 will be injected intravenously. Visual and semiquantitative method will be used to assess the PET/CT images.
详细描述
The glucagon-like peptide-1 receptor (GLP-1R) is an emerging target due to its high expression in benign insulinomas. 68Ga-NOTA-exendin-4 is an optimal probe targeting GLP-1R. The clinical use of 68Ga-NOTA-exendin-4 PET/CT in detecting insulinomas will be evaluated. And the comparation between PET diagnostic value and CT / MRI will be done.

研究组 & 干预措施
Patients will undergo 68Ga-NOTA-exendin-4 PET/CT imaging
A single dose of 37-111 Mega-Becquerel (MBq) 68Ga-NOTA-exendin-4 will be injected intravenously. PET/CT imaging will be performed at 30-60 min post-injection.Visual and semiquantitative method will be used to assess the PET/CT images.
干预措施: 68Ga-NOTA-exendin-4 (Drug)
