Preliminary study on the dynamic positron emission tomography imaging with 11 C-ER176 to delineate macrophage activation in diabetic gastroparesis.

C-ER 176 uptake in the stomach. Possible explanations include lack of specificity of ligand for specific macrophage phenotypes in DG, sex effect, or small sample size. Further studies investigating non-invasive ways of analyzing immune dysregulation in neurogastrointestinal disorders are warranted.
