Status: Completed

Conditions: Diabetes Mellitus, Type 2; Vascular Inflammation

Treatments: Drug: Atorvastatin 40 Mg Oral Tablet

Details and patient eligibility

About

To study the effect of atorvastatin treatment on vascular uptake of 68Ga-DOTATATE in patients with Type 2 Diabetes.

Full description

Well controlled patients with type 2 diabetes, who are statin naïve, will undergo atorvastatin treatment. Before and after treatment, patients will undergo a 68Ga-DOTATATE PET/CT, to evaluate the effect of treatment on vascular inflammation.

Enrollment: 24 patients
