Functional magnetic resonance (fMR) is a revolutionary neuroimaging technique. Despite challenges in hardware and analysis, fMR shows great promise for clinical and investigative neuroscience.

Area of Science:

  • Neuroscience
  • Medical Imaging

Context:

  • Functional magnetic resonance (fMR) imaging is a rapidly developing neuroimaging technique.
  • fMR presents significant hardware and data analysis challenges, including signal limitations, resolution constraints, and artifact management.

Purpose:

  • This paper reviews key aspects of fMR, focusing on signal origin, artifacts, and analytical methods.
  • The review is based on the blood-oxygen-level-dependent (BOLD) contrast, a common fMR technique.

Summary:

  • fMR imaging, particularly using BOLD contrast, offers insights into brain function.
  • Challenges include optimizing signal-to-noise ratio, correcting for motion, and refining statistical models.

Impact:

  • Despite being in its early stages, fMR is a valuable tool for both clinical diagnosis and scientific research.
