CT Scan

CT scans used to diagnose patients…
  • CT scans are more often used to assess bone injuries, problems in the lungs, or for cancer-related issues.
  • MRI scans are generally more detailed than x-rays and CT scans, however MRIs are better for viewing soft tissue, particularly tendons and ligaments. High resolution MRIs, such as a 3 Tesla MRI, are also ideal for examining tumors and other issues in the brain.
  • A CT scan only shows an image from one viewpoint. Images are horizontal and only display one slice of the interior of the object. An MRI, however, can produce an image from virtually any angle, and it shows you a 360-degree view of the object.
Exposure to Radiation
In recent years, people have started to worry about x-rays causing cancer. This is because x-rays are produced by ionizing radiation, which can be harmful to humans. With an MRI, on the other hand, there is no ionizing radiation and you are protected from any kind of harmful radiation because the machines use magnets instead of x-rays.
On the other hand, CT scans expose patients to low levels of radiation, which in extreme excess could lead to cancer. However, it’s important to note that one CT scan generates roughly the amount of radiation exposure one would normally receive in a span of three to five years. It’s not a lot, but repetitive exposure could become dangerous.
Process
CT scans are typically complete in five minutes or less. This minimizes patient discomfort and gets them in and out in much less time. Additionally, with CT scans patients aren’t required to lie perfectly still since a slight movement won’t really disrupt the imaging process.
