Summary
Functional MRI, using blood oxygen level dependent imaging, maps brain areas responsible for functions like movement and speech. This technique aids in surgical planning by identifying critical brain regions near abnormalities.
Area of Science:
- Neuroimaging
- Functional Neuroanatomy
Background:
- Functional Magnetic Resonance Imaging (fMRI) utilizes the blood oxygen level dependent (BOLD) technique.
- The BOLD technique acts as an endogenous contrast agent for neuroimaging.
Purpose of the Study:
- To elucidate the role of fMRI-BOLD in localizing eloquent cortex.
- To highlight the application of fMRI-BOLD in clinical management and surgical planning.
Main Methods:
- Employing functional MR imaging with the BOLD technique.
- Stimulating various motor and sensory tasks to elicit brain activity.
Main Results:
- fMRI-BOLD successfully localizes eloquent cortex during motor, sensory, visual, speech, and cerebellar tasks.
- Studies reveal significant information on cortical localization and functional control.
Conclusions:
- fMRI-BOLD is a valuable tool for mapping brain function.
- It is crucial for surgical planning, especially for lesions near eloquent cortex, to prevent neurological damage.

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...
Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
