使用氟化葡萄糖类似物、2-氟-2-脱氧-D-葡萄糖(2-FDG)或3-氟-3-脱氧-D-葡萄糖(3-FDG)和氟-19(19F)核磁共振(NMR)成像,在大鼠中无创地进行反映糖酵解和醛糖还原酶山梨醇(ARS)途径中葡萄糖代谢的代谢成像。 2-FDG-6-磷酸(2-FDG 在糖酵解途径中的主要代谢物)的 I9F 图像显示大脑、脊髓和心脏中的葡萄糖利用率很高。 3-氟-3-脱氧-D-山梨醇 (3-FDSL)(ARS 途径中 3-FDG 的主要代谢物)的图像证明了醛糖还原酶活性空间分布的异质性,在大脑和晶状体中最高。 3-FDG 的极低毒性预示着 3-FDG NMR 成像的临床应用前景。 © 1988 学术出版社
Metabolic imaging reflecting glucose metabolism in the glycolytic and aldose reductase sorbitol (ARS) pathways was performed noninvasively in rat using fluorinated glucose analogs, 2‐fluoro‐2‐deoxy‐D‐glucose (2‐FDG) or 3‐fluoro‐3‐deoxy‐D‐glucose (3‐FDG), and fluorine‐19 (19F) nuclear magnetic resonance (NMR) imaging. I9F images of 2‐FDG‐6‐phosphate, a main metabolite of 2‐FDG in the glycolytic pathway, showed high glucose utilization in the brain, spinal cord, and heart. Images of 3‐fluoro‐3‐deoxy‐D‐sorbitol (3‐FDSL), a main metabolite of 3‐FDG in the ARS pathway, demonstrated the heterogeneous nature of the spatial distribution of aldose reductase activities, being highest in the brain and lens. The extremely low toxicity of 3‐FDG indicates promise for clinical application of 3‐FDG NMR imaging. © 1988 Academic Press, Inc.
