Scan: As a noun, the data or image obtained from the examination of organs or regions of the body by gathering information with a sensing device. For specific scans, please see their alphabetical listings (such as Bone scan, CAT scan, Spiral CAT scan, Nuchal fold scan, and Thyroid scan).

CT scans can produce detailed images of many structures inside the body, including the internal organs, blood vessels and bones. They can be used to: diagnose conditions including damage to bones, injuries to internal organs, problems with blood flow, stroke, and cancer.

There are many different types of imaging, such as X-rays, CT (computed tomography) scans, MRI (magnetic resonance imaging) and ultrasound. Each imaging type uses a different technology to create an image.

Medical scanners are used to produce pictures of the human body. These images are utilised by healthcare professionals to evaluate and assist in the diagnosis of a disease state. This allows for the development of a personalised treatment plan for the patient.

There are several kinds of scan used depending on the area your doctor is examining. X-ray. Uses x-radiation to take images of dense tissues inside the body such as bones or tumours. Ultrasound. A scan that uses sound waves to create images from within the body.

The A-scan provides data on the length of the eye, which is a major determinant in common sight disorders. The most common use of the A-scan is to determine eye length for calculation of intraocular lens power. Briefly, the total refractive power of the emmetropic eye is approximately 60.

A computerised tomography (CT) scan uses X-rays and a computer to create detailed images of the inside of the body. CT scans are sometimes referred to as CAT scans or computed tomography scans.
