Benefits of MRI scans

  • See across multiple organs in a single scan

  • Spot structural changes—like signs of masses, abdominal aortic aneurysms, or liver lesions

  • No ionizing radiation, with detailed imaging of soft tissues

The bottom line:

MRI scans can look for early signs of cancer and hundreds of potential conditions

Benefits of CT scans

  • Fast scans that take just minutes

  • View of lungs and surrounding chest structures (Lungs CT Scan), and calcium buildup in the arteries of the heart (Heart CT Scan)

  • Helpful to look for early signs of conditions like lung nodules or assess for cardiovascular risk

The bottom line:

CT scans can help look for signs of lung cancer, calcium buildup in your heart’s blood vessels, and other serious health conditions.
