CT Scanners have long been a valuable diagnostic tool in today’s medical industry. They are powerful machines that can detect specific conditions that x-rays cannot because they can view the body in 3D. It is one of the must-haves in every health industry, which can help any company leverage other companies. 

If you run a medical facility, one would be an excellent investment. Here is your quick guide to CT scanners, so you will know what type you should get. 


MRIs vs CT Scanners: What’s the Difference?

When studying the body’s internal structure, the MRI and CT scan are two of the most commonly mentioned machines. They are used in similar ways, but they have different functions and purposes.

If a doctor needs to see minor changes in soft tissue, joints, ligaments, tendons, brain, and spine, the MRI might work better. It is best used to identify issues, detect problems, see body parts in detail, and monitor complications before they worsen. 

On the other hand, a doctor might ask to do a CT scan to get the bigger picture of a patient’s health. The CT scan can effectively do the following:

  • Diagnose any injuries from trauma
  • Check for developing tumors, including their size and location
  • Identify the stage cancer is in
  • Determine the kind of infection present
  • Detect the location of blood clots

Another important difference between the two is their speed. The CT scanner may take between five to twenty minutes, while the MRI would take around fifteen minutes to two hours, depending on the area of study. 


What CT Scanner’s Slices You Should Have

In the CT scanner’s language, “slices” refer to the cross-sectional images of a body part to be scanned. These slices form a cross-sectional 3D image of a human body. There are many slices in the market, but which is worth investing in? 

To give you an idea, here are the most commonly used slices:

  • 16 – best for clinics with a steady customer flow
  • 32 – similar to 16, although it has more features
  • 40 – similar to 32, although it has more features
  • 64 – the standard scanner you would see in hospitals
  • 128 – one of the top-notch scanners there is; can provide a whole-body scan in a few seconds
  • 256 – used to diagnose heart disease
  • 320 – can scan the whole body in less than a minute

The higher the number of slices, the better it can perform. With its help, the CT scanner could perform faster, reduced the scan times, lower radiation, and get more advanced imaging. 


When deciding, identify the kind of scan and scanner you would need for your clinic. Consider the number of patients you receive daily, the features you want, and how fast and wide the scanning should be. By identifying this data early, you would know the types of scanners to look into.
