Several different views of the head are available, including axial, coronal, reformatted coronal, and reformatted sagittal images. However, coronal images require the person to hyperextend their neck, which must be avoided if any possibility of neck injury exists. [8] CT scans of the head increase the risk of brain cancer, especially for ...
Structural magnetic resonance imaging (structural MRI) of a head, from top to base of the skull. The first chapter of the history of neuroimaging traces back to the Italian neuroscientist Angelo Mosso who invented the 'human circulation balance', which could non-invasively measure the redistribution of blood during emotional and intellectual activity.
The atlas was created from the brain of an unidentified 65-year-old man (it was "65-year-old female", according to "BigBrain: An Ultrahigh-Resolution3D Human Brain Model", page 1472, Amunts K et al, SCIENCE, 21 JUNE 2013 VOL 340) who died with no known brain pathology. His brain, after being removed from the skull, was first scanned using an ...
The superior temporal gyrus contains several important structures of the brain, including: Brodmann areas 41 and 42, marking the location of the auditory cortex, the cortical region responsible for the sensation of sound; Wernicke's area, Brodmann area 22, an important region for the processing of speech so that it can be understood as language.
T 1-weighted images are useful for visualizing normal anatomy. T 2-weighted (T2W) images: CSF is light, but fat (and thus white matter) is darker than with T 1. T 2-weighted images are useful for visualizing pathology. [26] Diffusion-weighted images (DWI): DWI uses the diffusion of water molecules to generate contrast in MR images.
Waters' view (also known as the occipitomental view or parietoacanthial projection) is a radiographic view of the skull.It is commonly used to get a better view of the maxillary sinuses.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body.
