Skull x Ray

An X-ray of the skull can reveal fractures, and may show changes from normal that suggest bleeding, tumours or an abscess within the skull. Enlargement of the bony cavity at the base of the skull in which the pituitary gland lies suggests tumours of the gland. However apart from detection of fractures, CAT SCANNING and MAGNETIC RESONANCE IMAGING provide more reliable information.

A skull x ray may detect bone fractures resulting from injury or disease. The skull x ray should clearly show the entire skull, jaw bones, and facial bones. Skull X-rays usually take about 10 to 20 minutes. In some clinics and hospitals, X-ray pictures can be made immediately on a computer screen. A skull X-ray is a series of pictures of the bones of the skull. In an emergency, the doctor can see the initial results of an extremity x-ray in a few minutes. Most experts feel that the risk is low compared with the benefits. Pregnant women and children are more sensitive to the risks associated with x-rays.

Why it is done?

• To check problems on a baby's head, such as an odd shaped skull.
• This test may be performed when there has been trauma and injury to the skull.
• The x-ray is also used to evaluate an unusually shaped child's head.
• Sinus x rays may be ordered to confirm a diagnosis of sinusitis, or sinus infection.

How to prepare?

• There is no preparation for the patient prior to arriving at the radiology facility.
• Before the X-ray test, tell your doctor if you are or might be pregnant.
• Patients will be asked to remove jewelry, dentures, or other metal objects that may produce artifacts on the film.
• If a skull X-ray is absolutely necessary, a lead apron will be placed over your abdomen to shield your baby from exposure to the X-rays.

What the risks are?

• There is low radiation exposure.
• Pregnant women and children are more sensitive to the risks associated with x-rays.
• The patient may feel some discomfort in the positioning of the head and neck, but will have no complications.
