A CT scan of the brain is the most common investigation in the setting of trauma. Bleeding is detected which may require neurosurgical intervention.
Non-traumatic causes of bleeds are also best assessed by CT.
A CT scan can be done with iodinated contrast material to look for infection or tumours.
High definition scans will detect skull and facial bone fractures and sinus disease.
A CTA (CT angiogram) is a special investigation to evaluate the intracranial vessels. Typically we would be looking for aneurysms or other vascular abnormalities.
