A CT scan of the coronal region of the brain is used in diagnosing tumours, lesions, injuries, bleeding in the brain, structural anomalies, infections, brain function changes, or other conditions. The CT scan images are used to analyse conditions like Fluid collection, such as an abscess, Haemorrhage, Hydrocephalus, Ischaemic process such as a stroke, glioma, meningioma, craniopharyngioma, nasopharyngeal carcinoma and other such conditions.
A head holder is used for performing brain CT if a head holder is not there then a moulded sponge is placed on the scan table and the patient's head is positioned with the sponge. The patient is made comfortable and steady in both the cases to prevent abstracts in the final image. A coronal position can be achieved by Placing the patient in prone position on the scanning table and ask the patient to extend the chin forward. It can also be achieved by Placing the patient supine and ask him to drop his head back as far as possible.
