CT Scan

CT (Computed Tomography) This specialised exam produces cross-sectional images of the internal body parts and organs, especially of those organs that are in a state of constant motion e.g. heart/lungs. The complete examination lasts between 5 to 10 minutes. 

CT Extremity

CT Skull

CT Lungs

CT Heart

CT Organs, abdominal cavity

The clinics that work in conjunction with Prescan use the most advanced scanning machines, such as the latest Siemens scanning system. We also have an open scanner, which is more comfortable for claustrophobic patients. 

The clinics that carry out the examinations make use of CT scanning technology to obtain a concise and clear image of organs such as the heart and lungs. CT scans make use of X-ray or gamma radiation technology. The regulatory requirements concerning the limitation of radiation dose are strictly adhered to. 


The lungs are scanned if:

  • The client is 40 years or older, smoking and has smoked one packet of cigarettes per day for the last 10 years. 

  • The client is 40 years or older, who stopped smoking, less than 15 years ago after having smoked one packet of cigarettes a day for at least 10 years.

This data is based on the interim conclusions drawn by I-Elcap screening for Lung cancer, and updated in early 2004. 

Clients above 40 years of age will have a section of the lungs included in the picture when undergoing the CT of the heart.

The heart will be scanned in the following instances:

With clients in the age group 40-75 years, and at least one of the following risk factors is present: 

  • Smoking
  • High cholesterol levels
  • Diabetes
  • The occurrence of a heart infarct at a young age in the family
    (younger than 70)

If the above-mentioned criteria are not applicable to you, then the CT of the heart will be substituted for an echocardiogram in combination with an ECG examination. If you have cardiac medical history (e.g. stent/s, bypasses or previous infarcts) it is required of you to state this in the medical history. An alternative possibility will then be discussed. 

On your doctor's advice it may be necessary to make use of a contrast agent to improve the quality of the images/pictures made. 

In some rare cases it is possible that allergic reactions can occur. This can be in the form of nausea, an increased tendency to sneeze or a rash. These reactions generally stabilise within a short time. 

In rare cases extreme allergic reactions can occur, such as: disturbances in the blood circulatory system, liver, kidneys and /or nerves. These unpredictable side effects can make it necessary to be admitted to hospital. The results of which can cause permanent damage.
