Representative examples of Rubidium-PET myocardial perfusion imaging (MPI) of diabetic patients with normoalbuminuria (A) and macroalbuminuria (B). No myocardial ischemia was present on Rb-PET MPI (a), nor coronary calcification on the low-dose CT used for attenuation correction of PET images (b) in both patients. Quantification of myocardial blood flow (MBF) with Rb-PET evidenced the presence of a global normal stress MBF and myocardial flow reserve in favor of a normal cardiac microvascular function (MFR = 5.1) in normoalbuminuric patient and a global low stress MBF and myocardial flow reserve in favor of cardiac microvascular dysfunction (MFR = 1.6) in macroalbuminuric patient (c)
