What is the Difference Between a CT Scan and an MRI?

CT Scan of brain vs MRI
A: CT scan of the brain showing hypodensity of the right frontal lobe of the brain. B: T1-weighted MRI scan of the same brain showing hypointensity of the lesion. C: T2-weighted MRI scan of the same brain showing hyperintensity of the lesion.

While both CT scans and MRIs have unique benefits, there are significant differences between them. Most notably, a CT scan detects changes and abnormalities in hard tissues. An MRI can provide additional detail about both hard and soft tissues. For this reason, radiologists, oncologists, and other healthcare professionals often order MRI scans when performing cancer screenings and diagnosing diseases.

What is a CT Scan?

A CT scan, or computed tomography scan, involves a large X-ray machine. Patients are typically asked to lie down during a CT scan while the X-ray machine takes cross-sectional pictures of the hard tissues inside their bodies. Doctors frequently order CT scans when they suspect that a patient has suffered from a specific type of injury. They’re useful in diagnosing and examining:

  • Fractures
  • Tumors
  • Cancer monitoring and staging
  • Internal bleeding
  • Head trauma
  • Evaluating post-surgical success

A CT scan can also help guide doctors through procedures, such as biopsies and surgeries. It is minimally invasive and can be performed quickly and easily.

What is an MRI?

An MRI is similar to a CT scan, however, it offers a more detailed look inside the body at various hard and soft tissues. The MRI machine uses magnets and radio waves to give doctors a full image of the tissues and structures inside your body. They’re especially helpful when diagnosing:

  • Detecting certain cancers, such as prostate cancer or liver cancer.
  • Soft tissue injuries
  • Heart issues
  • Torn ligaments
  • Herniated disks

MRIs are also helpful in the diagnosis of early-stage breast cancer because they can detect tumors before they become larger.

Choosing Between an MRI and a CT Scan

Depending on your issues, your doctor may order either a CT scan or an MRI. In many cases, CT scans are ordered first to get a clear immediate picture of the hard tissues in the body, including tumors, etc. Then doctors order an MRI later if they see something on a CT scan that they’re unsure of.

However, MRI and CT scans should be considered complementary rather than the opposite. Many oncologists, radiologists, and medical professionals use both scans to make a complete diagnosis or to develop a more comprehensive treatment plan.

Both MRI and CT provide invaluable information that can be useful to your healthcare providers.
