Area of Science:

  • Neurology
  • Radiology
  • Medical Imaging

Background:

  • T2-weighted MR imaging identifies infarcted tissue but not acute ischemia.
  • Distinguishing acute from chronic stroke is challenging due to similar T2 signal intensities.
  • Diffusion imaging offers potential for acute ischemic stroke treatment guidance.

Purpose of the Study:

  • To highlight the potential of diffusion imaging in acute ischemic stroke.
  • To address controversies regarding diffusion changes and reperfusion.
  • To improve the reproducibility of diffusion imaging.

Main Methods:

  • Utilizing magnetic resonance (MR) diffusion imaging.
  • Analyzing the temporal evolution of diffusion characteristics.
  • Employing optimal diffusion imaging strategies.
