What is a CT scan?
A CT scan, or computerised tomography, is a means of medical testing that combines a series of X-ray images and computer processing to create cross-sectional visuals of the inside of the body. X-ray images are taken at a variety of different angles that provide a detailed view of bones, organs, soft tissues and blood vessels.
This means of testing is a highly accurate way for medical professionals to quickly examine a person who may have serious internal injury or bodily trauma. A doctor can see just about the entire body using the technology of this visual imaging test. The highly-detailed images created provide much needed visual information that enables a medical doctor to accurately diagnose a problem, disease, injury or abnormality. In turn, the most effective means of treatment can be implemented, lowering the risk of further damage.
Key areas of the body a doctor may recommend a scan to gain a better perspective of include:
- The head
- The spine
- The shoulders
- The chest
- The heart
- The abdomen
- The knees
The series of images taken during the testing procedure are combined using computerised software that creates cross-sections or slices to form detailed images of the inside of the body. Here, any abnormalities will be clearly shown and easily diagnosed. A 3-D image can be created of a particular area of the body for medical professionals to gain a clearer idea as to what may be malfunctioning or damaged, and make a more accurate diagnosis.
A CT scan is minimally invasive and is a completely painless experience. It can also be done relatively quickly, which can be very useful in time-sensitive medical situations.
