Imaging exams are often used to determine if a patient's ventricles are enlarged.

Computerized Axial Tomography (CT or CAT) Scan is a commonly performed imaging procedure that is noninvasive and well-tolerated. It produces cross-sectional images that allow doctors to look at the inside of many different parts of the body and/or brain. CT uses x-rays to produce these images.

Magnetic Resonance Imaging (MRI) is often used to further evaluate an abnormality seen on a CT scan. This is an imaging technique that uses strong magnetic radio waves to produce high quality images of the inside of the human body or brain. It is widely used when a diagnosis of NPH is being considered as it provides important detail of the ventricular system and can help to rule out other disorders, e.g. subdural haematoma, tumor, infection, or a structural abnormality.
