Neuroimaging Techniques
Neuroimaging Techniques
Several remarkable technological advancements make understanding the brain’s inner workings possible. Neuroimaging methods are used in the medical, psychological, and scientific communities to visualize the structure and function of the neurological system. The current developments in neuroimaging enable the capture of brain activity at an increasing spatial and temporal resolution, although brain data are multimodal and complicated by nature (Erol & Hunyadi, 2022). This article examines various neuroimaging methods, including their advantages and disadvantages.

Computed Tomography (CT) imaging provides reliable and timely medical and surgical intervention information. CT is a computerized x-ray imaging method where the individual is exposed to a beam of rotating x-ray radiation, which is subsequently translated into cross-sectional “slices” of the particular area viewed by the computer (Singh & Sandean, 2021). CT scans of the brain provide more detailed information on the organ’s structure and tissue than standard X-rays of the skull and brain. It is non-invasive, quick, easy, and economical. The dangers of CT scanning include long-term cancer growth owing to radiation exposure, pregnancy damage, contrast-induced allergic responses, and nephropathy.
Magnetic resonance imaging (MRI) is an imaging modality that can show better contrasts in soft tissues and be used for physiological and functional purposes. Magnetic resonance imaging uses a strong magnetic field, radio frequencies, and a computer to create high-resolution images (Ghadimi & Sapra, 2020). MRI can more precisely differentiate between muscle, fat, water, and other soft tissues than CT. Conversely, the strong, static magnetic field’s attraction to metallic magnetic objects may harm the patient or medical workers (Ghadimi & Sapra, 2020). MRI occasionally makes loud noises that could damage hearing, the contrast chemicals used can cause allergic reactions, and the output can be affected by patient movement. Today, various brain imaging methods are employed, each presenting the brain differently, with different benefits and risks.
