Structural and functional magnetic resonance imaging (sMRI and fMRI) are the most commonly used techniques in studying central nervous system diseases. This article reviews recent technological research to provide evidence for acupuncture research and development. </span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-US">Materials and Methods: </span></span></span></span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="language:en-US">Relevant articles were obtained from PubMed and China national knowledge infrastructure (CNKI) databases, as well as from CNKI database from 2014 to 2023.

As MRI technology rapidly evolves, additional techniques such as diffusion kurtosis imaging (DKI), diffusion spectrum imaging (DSI), and neurite orientation dispersion and density imaging (NODDI) can be used to observe post-IS motor neural injuries and related neural reshaping. </span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-US">Conclusions: </span></span></span></span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="language:en-US">These techniques about MRI could help doctors better understand the biological mechanisms underlying neural pathways and motor deficits in IS, aiding in the development of targeted therapies.</span></span></span></span></span></span></span></span></span></div> Acupuncture, stroke, motor function impairment, hemiparesis, neuroplasticity, MRI. 647 655 http://ijrr.com/browse.php?a_code=A-10-1-1221&slc_lang=en&sid=1 Y.
