fMRI is a brain scan that measures blood flow and neuronal activity in the brain or spinal cord. It uses MRI technology and the blood-oxygen-level dependent (BOLD) contrast to detect changes in oxygenation related to brain function.
Learn about the history, applications and techniques of MRI of the brain, a non-invasive imaging modality that uses magnetic fields and radio waves. See examples of T1, T2, DWI and FLAIR images of normal and abnormal brain anatomy.
Magnetic resonance neurography (MRN) is a modification of MRI that images nerves by optimizing their water properties. It is used to evaluate nerve compressions, injuries, irritations and other disorders.
Learn about the medical imaging technique that uses strong magnetic fields, radio waves and nuclear spin to create images of the body. Find out how MRI works, what it is used for, what are its advantages and disadvantages, and how it differs from other scans.
Neuroimaging is the use of quantitative techniques to study the structure and function of the central nervous system, developed as an objective way of scientifically studying the healthy human brain. Learn about the history of neuroimaging, from the first brain circulation balance to the latest MRI and fMRI methods, and the indications and applications of neuroradiology.
Learn how MRI uses nuclear spin and radio frequency to generate images of the body. Find out the history, principles, and applications of MRI, and the difference between 3 tesla and other field strengths.
HDFT is based on data acquired from diffusion spectrum imaging [2] and processed by generalized q-sampling imaging. [3] [4] The technique makes it possible to virtually dissect 40 major fiber tracts in the brain. [1] The HDFT scan is consistent with brain anatomy unlike diffusion tensor imaging . [5]
Functional magnetic resonance spectroscopy of the brain (fMRS) uses magnetic resonance imaging (MRI) to study brain metabolism during brain activation. The data generated by fMRS usually shows spectra of resonances, instead of a brain image, as with MRI. The area under peaks in the spectrum represents relative concentrations of metabolites.
