Diagnostic Imaging

November 7 2016

World Radiography Day is celebrated every 8th November and marks the anniversary of the discovery of x-radiation by Wilhelm Roentgen in 1895. Paul Hayllar, Diagnostic Imaging Manager at Southampton NHS Treatment Centre and the Royal South Hants MIU, describes the various diagnostic imaging methods used at the centres.

Magnetic resonance imaging (MRI) is a type of scan that uses magnetic fields and radio waves to diagnose conditions that affect the tissue and bone in any part of the body. The patient lies inside the scanner - a large tube - while the scan takes place.

An ultrasound scan builds up a picture of part of the inside of the body using sound waves that cannot be detected by a human ear. A small, hand-held sensor is pressed carefully against the skin surface above the area to be viewed. The ultrasound scan does not use or produce ionizing radiation. It is an easy and useful diagnostic method.

X-rays are used by medical professionals to image various parts of the human body to aid diagnosis. Diagnostic X-rays are a controlled form of radiation which are able to pass through the body recording an image on a light-sensitive detector or computer screen.
