What is the difference between MRI and CT scan of head?
A typical CT scan lasts 10 minutes whereas MRIs can take up to an hour or longer.
Images: MRIs will produce sharper, more detailed results, especially of soft tissues and behind bones, which may block views on CT scans..
What is the indication of brain computed tomography?
Indications.
A CT brain is ordered to look at the structures of the brain and evaluate for the presence of pathology, such as mass/tumor, fluid collection (such as an abcess), ischemic processes (such as a stroke).
It is particularly good for hemorrhage, trauma or fracture to the skull and for hydrocephalus..
What is the technique of CT brain?
For CT Brain, axial images are obtained covering from top of the head to the base skull including the orbits.
The section thickness in mutislice CT is usually less than 1.0 mm.
However, for imaging documentation 5 mm slices are reconstructed and printed.
The radiation dose is usually less than 2 mSV..
What will a CT scan show of the head?
A CT of the brain may be performed to assess the brain for tumors and other lesions, injuries, intracranial bleeding, structural anomalies (e.g., hydrocephalus , infections, brain function or other conditions), particularly when another type of examination (e.g., X-rays or a physical exam) are inconclusive..
Examine the brain for:
- Symmetry - make sure sulci and gyri appear the same on both sides
- Grey-white differentiation - the earliest sign of a CVA on CT scan is the loss of the grey-white interface on CT scan
- Shift - the falx should be in the midline with ventricles the same on both sides
- One term that becomes a hot topic of every conversation with the company's HR is the Cost-To-Company or CTC.
The CTC involves all the variable payments that the companies make along with the basic salary to the employees and is considered the total cost incurred by the company to hire a new employee.
