Question

How to distinguish between plain and contrast enhanced ct brain?

Answer 1

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.

1.Bone abnormalities

2.Brain mass/tumor

3.Fluid collection, such as an abcess

4.Hemorrhage

5.Hydrocephalus

6.Ischemic process, such as a stroke

7.Trauma or fracture of the skull  

Contrast

CT of the brain can be done with or without contrast, but it is often not needed. In general, it is preferred that the choice of contrast or no contrast be left up to the discretion of the imaging physician.
