We recently reported a new NOE-mediated MT signal at around -1.6 ppm, named NOE(-1.6). In the present work, we evaluated the changes of this signal that occur early in ischemic stroke and found that both NOE(-1.6) and Amide Proton Transfer (APT) signals from stroke lesions have significant changes after MCAO. Compared with APT, NOE(-1.6) showed much stronger contrast between stroke and contralateral normal tissues. We conclude that a new NOE(-1.6) signal in rat brain could be used as a biomarker for assessment of acute ischemic stroke.
