Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Background:

Functional magnetic resonance imaging (fMRI) is vital for mapping the visual cortex pre-surgically.
This mapping balances therapeutic outcomes with preventing postoperative vision deficits.

Purpose of the Study:

To detail clinically optimized fMRI techniques for visual cortex mapping.
To identify cortical subregions essential for high-acuity central vision.

Main Methods:

Utilized clinically optimized stimuli, behavioral tasks, analysis, and displays.
Focused on identifying specific cortical subregions supporting vision.

Main Results:

Established methods for precise identification of visual cortex subregions.
Demonstrated the critical role of these subregions in reading and essential visual functions.

Conclusions:

Clinically optimized fMRI enables precise visual cortex mapping for surgical planning.
Emerging techniques like resting-state fMRI may expand fMRI vision mapping accessibility to more patients.
