Application of functional imaging in diagnosis of diabetes mellitus / 中华内分泌代谢杂志

ABSTRACT

In either type 1 or type 2 diabetes,there is significant loss of β cell mass.Understanding the changing of β cell mass in the course of diabetes would provide important information for diagnosis and treatment.Functional imaging like magnetic resonance imaging or positron emission tomography (PET) can provide safe and noninvasive detection of loss of β cell mass in the course of diabetes.Among them,radio-labelled imaging is the most sensitive imaging procedure of the β cell ; For dihydrotetrabenazine PET imaging aiming β cell mass,there has been some primary outcome.For the key factor causing type 2 diabetes,18 F-6-deoxy-6-fluoro-D-glucose (18F-6-FDG) PET imaging is an effective tracer to study the glucose transporting condition in vivo.Further development of functional imaging will be of great value in diagnosis and treatment of diabetes.
