The brain is divided into four pairs of lobes, including the frontal lobes, the temporal lobes, the parietal lobes and the occipital lobes. At the center of the brain, there are paired thalami and basal ganglia (caudate nucleus, putamen and globus pallidus). Around these structures swirls the ventricular system, which includes the two lateral ventricles, the third ventricles, and the fourth ventricle. The brain is covered by three layers of protective tissue.
Computed Tomography (CT) of the head displays cross sectional slices of the brain. Keep in mind that- “left side of the picture represents the right side of the patient’s brain.”
The film is divided into little boxes, which are read from left to right much like the pages of a book. The patient’s identification (ID) is in the first box. This is followed by a lateral view of the patient’s head called the “scout view”.
On this view, superimposed lines show where the CT images have been taken. Although many slices are presents on a CT scan film, there only 6 that are necessary to memorize. From the base of the brain to the top of the skull, these include:-
1. The X,
2. The star,
3. Mr. Happy,
4. Mr. Sad,
5. The worms, and
6. The coffee bean.
simple to memorize !!!
