Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of brain scan is useful for looking at the structure of the brain?
A
CT Scan
B
PET
C
fMRI
D
EEG
E
MRI
Explanation: 

Detailed explanation-1: -Brain CT scans can provide more detailed information about brain tissue and brain structures than standard X-rays of the head, thus providing more data related to injuries and/or diseases of the brain. During a brain CT, the X-ray beam moves in a circle around the body, allowing many different views of the brain.

Detailed explanation-2: -Researchers use a variety of neuroimaging tools to study the brain. Computed tomography (CT) scans are oblique X-ray slices that show the density of brain structures. Magnetic resonance imaging (MRI) uses changes in electrically charged molecules in a magnetic field to form images of the brain.

Detailed explanation-3: -A CT scan can detect conditions of the brain, like stroke and vascular dementia. The images produced by a CT scan provide detailed information about brain tissue and brain structures.

Detailed explanation-4: -Magnetic resonance imaging produces clearer images compared to a CT scan. In instances when doctors need a view of soft tissues, an MRI is a better option than x-rays or CTs. MRIs can create better pictures of organs and soft tissues, such as torn ligaments and herniated discs, compared to CT images.
