E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to evaluate the difference in 68Ga-exendin tracer accumulation in the pancreas of patients with and without complete resolution of T2DM after RYGB by quantitative analysis of PET images. |
Het primaire doel is om het verschil in de opname van de radioactief gelabelde tracer 68Ga-exendin in de pacreas van patienten met en zonder complete remissie van type 2 diabetes na het ondergaan van een Roux en Y gastric bypass operatie te vergelijken door middel van kwantitatieve analyse van PET beelden. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objective is to determine the correlation between 68Ga-exendin tracer
accumulation and beta cell function of the patients as assessed by oral glucose tolerance
testing and arginine stimulation. |
Het secundaire doel in om de correlatie te bepalen tussen de opname van 68Ga-exendin en de beta cel-functie van patienten, bepaald dmv glucose-tolerantietest and arginine-stimulatie |
|
E.2.3 | Trial contains a sub-study | No |
