Type 1 diabetes was induced in rats by a single-dose intraperitoneal injection of streptozotocin (STZ). High resolution anatomical images were acquired with a RARE sequence and in vivo 1H spectra of the visual cortex by a PRESS sequence at 12 weeks after induction. The STZ-treated rats showed significantly increased myo-inositol/creatine ratio, and significantly reduced NAA/creatine ratio and thickness in the visual cortex. These results indicated that chronic diabetic complications involves anatomical and metabolic changes in the visual cortex.
