A Scan Of The Different Neuroimaging Techniques

Neuroimaging techniques have allowed neuroengineers to view brain activities and have aided in diagnosing brain-based problems. The rapid progress of technology has helped develop the efficiency of old imaging models, while also yielding new imaging techniques. Some of these are listed below.

MRI: The magnetic resonance imaging technique is designed to give a snapshot of the anatomical structure of the brain to diagnose brain ailments. It uses magnetic fields and radio waves to create high-quality two- or three-dimensional images of the brain structure.

fMRI: Similar to MRI, functional magnetic resonance imaging measures anatomical brain engagement or how well brain systems work with one another. It detects changes in blood oxygenation and flow due to neural activities.

CT scan: Computed tomography scanning produces an image of the brain based on the differential absorption of X-rays. But with even less resolution than MRI, it is too slow to measure neuro-function.

PET and SPECT: Positron emission tomography and singe-photon emission computed tomography measure metabolic activities within cranial areas. Functional processes in the brain are mapped using short-lived radioactive tracers.

QEEG: Quantitative electroencephalography can measure neuro-function down to a 100th of a millisecond, which is close enough to the processing speed of brain function. A faster recording time means the brain performance can be measured more clearly.
