The Differences Between CT Scanners and MRI Machines

Posted by kktchillersusa on April 23rd, 2019

Magnetic resonance imaging (MRI) machines and computerized tomography (CT) scanners are used by medical professionals across the world to capture images of a patient's body. These machines play a vital role in modern health care since they're able to provide detailed images of the human body. These detailed images allow doctors to diagnose illnesses better and provide patients with the right treatments. While doctors are usually the ones who decide which machine will be used for your specific needs, it's also essential to learn the differences between CT scanners and MRI machines. Keeping them cool is what keeps them working well.

CT Scanners

CT scanners combine a series of X-ray images taken from various angles around the body. The images are then processed by a computer to generate cross-sectional images or "slices." CT scanners can reveal anatomic details of the patient's internal organs that can't be detected by conventional X-rays. Without chillers, the machine could overheat, which would negatively impact results.

Doctors would usually use a CT scanner for:

  • Detecting internal injuries and internal bleeding
  • Guiding procedures such as surgery and biopsy
  • Locating an infection, tumor, or blood clot
  • Diagnosing diseases such as cancer and heart disease
  • Monitoring the effectiveness of various medical treatments

According to the American College of Radiology, CT scans should only be done when there are clear medical benefits. While it's true that CT scans are safe and use low levels of radiation, frequent CT scans may increase the risk of developing cancer due to too much exposure to radiation. It's best to ask a doctor if a CT scan is required for your condition before proceeding.

MRI Machines

MRI machines use powerful radio waves and magnets to create detailed images of internal organs and tissues. Since MRI machines produce a tremendous amount of heat, they need an MRI cooling system to keep them running efficiently.

While CT scans are more widely used and are typically less expensive than MRIs, the latter is believed to be superior in terms of the detail of the images produced. Doctors are more likely to use MRI if they need comprehensive images of your organs, ligaments, or soft tissues. MRIs are often performed when diagnosing brain injuries caused by trauma, eye and inner ear disorders, and many others.

 Since MRI machines use powerful magnets, patients are required to remove any metallic objects from their body as they may pose a safety hazard. Most medical facilities have comprehensive screening procedures and protocols to ensure the safety of their patients as well as their staff.

 MRI and CT scans are essential in the health care industry. Even the machines themselves, and protective equipment like an MRI cooling system, are critical in producing accurate medical results. Both the machines and the processes allow doctors to provide their patients with comprehensive diagnoses and effective treatments.
