Cranial CT Anatomy: A simple image guide for medical students

cranial ct anatomy

Computed tomography (CT) is the most useful brain imaging tool in emergency medical practice. It is also the first imaging modality in patients presenting to the emergency department with headache, stroke and head trauma.

Many cranial lesions can easily be recognized in CT. One of the key points of diagnosing cranial lesions is knowing the anatomical structures. This gives us the advantage to evaluate CT by combining clinical findings with the image.

We created an image series for the most essential eight anatomical structures.
