Take a look at the following example. Let us go through how we would systematically analyse this and the diagnosis.

Analysis and Diagnosis
D – This is a CT Head taken on ….., of the following patient….. Is there a previous CT scan to compare to?
“On initial inspection, there appears to be an intracranial bleed, but I will proceed to go through it systematically.”
B – Looking at the film, there is a convex shaped density in the left side over the pterion. This is indicative of an extradural bleed.
C – The cisterns are clear and no sing of a subarachnoid haemorrhage.
B – The appears to me slight shifting of the brain tissue across the midline to the right. There is no area of hypo/hyperdensity and no obvious masses or ring-enhancing lesions.
V – The ventricles are not enlarged and there is no signs of an intraventricular bleed.
B – There appears to be damage to the skull over the left pterion.
