Brain Amide Proton Transfer Imaging of Rat With Alzheimer’s Disease Using Saturation With Frequency Alternating RF Irradiation Method

Published on August 23, 2019

Amyloid-β (Aβ) deposits and some proteins play some essential roles in AD pathogenesis. Amide proton transfer (APT) imaging as an indicator of tissue protein has shown promise for AD diseases. In this study, we chose 20 AD model rats as the experimental group and 20 sham-operated rats as the control group. They were firstly underwent Y-maze test, and then performed on a 7.0 T animal MRI scanner to acquire brain amide proton transfer image using saturation with frequency alternating RF irradiation (APTSAFARI) method. Compared with the control group, APT (3.5ppm) values of brain were significantly reduced in AD models (p
