Advanced Uses of Brain CT Scan

Abstract

The techniques covered in the preceding chapters are reviewed with more complex examples to illustrate the point that advanced inference is a function of carefully applying the basic principles we have learnt. The examples include a case of severe traumatic hematoma with herniation that has superimposed imaging artefacts. Aptly titled “when chaos becomes a concept”, it illustrates the reliability of the basic principles even in complicated situations. Advanced imaging techniques are mentioned for the advanced reader to explore independently.

CT angiography and CT venography with 3D rendition is widespread but functional imaging modalities such as CT perfusion are less common. A brief mention is made of the principles CT scanning in this section rather than at the beginning to emphasize that this knowledge is not required to interpret a brain CT scan just as you do not need to be an automotive engineer to drive a car.
