    • The present invention provides non-invasive methods for determining the beta cell mass in the pancreas of a subject by administering to the subject an effective amount of a vesicular monoamine transporter type 2 (VMAT2)-specific radioligand; obtaining at least one computerized image of at least a portion of the pancreas of the subject; and quantitatively analyzing the computerized image in order to determine the beta cell mass in the pancreas of the subject. The present invention additionally provides methods for diagnosing a metabolic neuroendocrine disorder in a subject including insulinoma, diabetes and preclinical diabetes, as well as methods for determining the efficacy of treatment for a metabolic disorder. The present invention further provides methods for assessing the prognosis of a subject at risk for developing diabetes, and methods for managing the treatment or prevention of diabetes. The present invention also provides kits for use in determining the beta cell mass in the pancreas of a subject, as well as diagnosing metabolic or neuroendocrine disorders in a subject.
    • 本发明提供了通过向受试者施用有效量的2型(VMAT2)特异性囊泡单体转运蛋白来确定受试者胰腺中的β细胞团的非侵入性方法; 获得所述受试者的胰脏的至少一部分的至少一个计算机化图像; 并定量分析计算机化图像,以确定受试者胰腺中的β细胞量。 本发明另外提供了用于诊断包括胰岛素瘤,糖尿病和临床前糖尿病的受试者中的代谢神经内分泌障碍的方法以及用于确定治疗代谢紊乱的功效的方法。 本发明还提供了评估患有糖尿病风险的受试者的预后的方法,以及用于治疗或预防糖尿病的方法。 本发明还提供了用于确定受试者胰腺中的β细胞群以及诊断受试者中代谢或神经内分泌障碍的试剂盒。
