    • 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泡状单胺转运蛋白2型(VMAT2)特异性放射性配体来确定受试者胰腺中β细胞量的非侵入性方法; 获得对象的至少一部分胰腺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受试者中的代谢性神经内分泌紊乱的方法,所述紊乱包括胰岛瘤,糖尿病和临床前糖尿病,以及用于确定治疗代谢紊乱的功效的方法。 本发明进一步提供了评估处于发展糖尿病风险中的受试者的预后的方法,以及用于管理糖尿病的治疗或预防的方法。 本发明还提供用于测定受试者胰腺中的β细胞量以及诊断受试者中的代谢或神经内分泌紊乱的试剂盒。
