Overview

A CT scan of the head is an important diagnostic tool in cases of confusion where a cause couldn't be established. Before a lumbar puncture is done, a CT scan is the first test used in cases of suspected infections such as meningitis.

CT

This test is not done as part of a routine evaluation for confusion. It is ordered when no significant cause is established.

• CT scan of the head has to be performed before proceeding to a lumbar puncture.
• CT scan of the head helps in identifying any lesions of the brain causing confusion.
• A CT aids in identifying associated co morbid conditions of the brain.
• It is needed when it's tough to get a history from the patient and other causes can't be established.
• It is ordered when a patient is not responding to treatment.
• It is helpful in finding primary sites of the tumor in cases of confusion caused by metastatic lesions of the brain.
