A to Z of services

X-ray (plain radiography) is a diagnostic test using x-radiation and computer technology to produce a two dimensional picture of the inside of the body. It is often used as a first line imaging test to look for evidence of injury or disease.

The test is carried out by a radiographer, who positions the patient between the x-ray machine and the x-ray detector. A beam of x-rays is passed through the patient which is not felt by the patient.

The exposure time is a fraction of a second. Some types of body tissue (e.g. bone) stop more of the x-rays than others (e.g. lung). This determines the amount of x-rays that reach the detector, which allows a diagnostic image to be produced. The image is stored on a computer.

The procedure may be performed with the patient standing, sitting or lying down, depending on which body part is being imaged. Several images (projections) may be required for a single examination.

We provide a walk-in service for x-ray at both Croydon University Hospital and Purley War Memorial Hospital.

• Saturday & Sunday between 9am and 12.15pm

Purley War Memorial Hospital:

You do not need an appointment to attend our walk-in service, but you must have a referral from your doctor. These are usually sent to us electronically although you may be provided with a paper copy (which we do not require).  X-ray requests are valid for 6 weeks from date of referral.
