Evaluation of right ventricular myocardial microcirculation in diabetes patients by using optimized intravoxel incoherent motion imaging

Intra-voxel incoherent motion imaging (IVIM) can noninvasively and quantitatively evaluate myocardial microcirculation. At present, some scholars have demonstrated that IVIM can observe left ventricular myocardial microcirculation. However, due to the thickness of the right ventricular wall, IVIM imaging is difficult to assess it. This study proposed an optimized navigator-based and free-breathing acquisition scheme for cardiac IVIM. The results found that right ventricular myocardial microcirculation was impaired, pseudo-diffusion coefficient (Dfast) were significantly lower than healthy volunteers. It is helpful to monitor cardiovascular risk and evaluate prognosis.
