Magnetic resonance (MR) offers three main techniques for studying brain function: BOLD fMRI, 3D anisotropy contrast axonography, and spectroscopic imaging. BOLD fMRI and 3D anisotropy contrast axonography show the most promise for clinical applications.

Area of Science:

Medical science
Neuroimaging
Biophysics

Context:

Magnetic resonance (MR) is a versatile technology with broad applications in medical science.
Current MR techniques allow detailed probing of human brain function.
Three primary categories of MR techniques are available.

Purpose:

To categorize and describe the main MR techniques for human brain function analysis.
To highlight the clinical potential of different MR modalities.

Summary:

The first category includes Blood Oxygenation Level Dependent (BOLD) functional magnetic resonance imaging (fMRI), which utilizes metabolic effects of brain activation.
The second category involves three dimensional anisotropy contrast (3DAC) axonography for probing axonal connectivity via diffusion tensor imaging.

The third category is spectroscopic imaging (SI), a biological application of nuclear magnetic resonance (NMR) spectroscopy for in vivo biochemical analysis.

Impact:

BOLD fMRI and 3DAC axonography are identified as having the highest potential for direct clinical applications.
This categorization provides a framework for understanding and applying advanced MR techniques in neuroscience and medicine.
