CT Scan Basics
A CT scan is like a super-detailed X-ray. It uses special X-ray beams to create pictures.
An MRI doesn’t use X-rays. Instead, it uses powerful magnets and radio waves to make images.
CT scans are great for seeing bones and finding injuries quickly.
MRIs are excellent for looking at muscles, the brain, and the spine in detail.
A CT scan is usually faster, taking only a few minutes, while an MRI can take up to an hour.
MRIs are loud! They make a knocking noise, but you'll get earplugs to help block the sound.
Sometimes, a special dye is used in both scans to make the pictures clearer.
For both scans, you need to lie very still to get a good picture.
CT scans use a bit of radiation, but don’t worry, it’s very safe. MRI uses no radiation.
People with certain metal implants can’t have MRIs because of the magnets.
Doctors decide which test you need based on what they need to see inside your body.
