MRI studies of retinal oxygenation in diabetic retinopathy / 中国医学影像技术

ABSTRACT

The function of the retina is sensitive to oxygen tension, and any changes in oxygen perfusion associated with retinal vessel diseases, such as diabetic retinopathy could affect inner retinal oxygen responses (ΔPO_2). However, the application of currently available techniques in measurements of the retinal oxygenation is limited. Recently, with the development of MRI, it is possible to detect ΔPO_2 noninvasively, and the effects are satisfactory. The application of MR based measurements of ΔPO_2 following the shift from breathing room air were reviewed in this article.
