Basic anatomy of CT brain
a) Various Densities in Axial Brain CT The normal anatomy of brain is relatively easier to understand with CT than MRI, comparing to radiograph, it can better delineate different soft tissue density – Structures appearing “white” in an unenhanced CT brain can only be the following high density structures : 1. Bone e.g. cranium ( calcium-containing ) 2. Blood in acute bleeding ( later…
Basic principles of CT brain
a) Principles of CT scan Computed Tomography (CT) is an imaging modality that uses computer-generated analysis ( i.e. computed ) of the x-ray attenuation through a section of the body tissue to produce cross-sectional images ( i.e. tomography ) with great anatomical details. Unlike plain X-ray images which are projected images of one plane, CT…
