The Difference between an X Ray and MRI, Ultrasound and CT Scan EXPLAINED in simple terms (easy to understand).

At some point in our life we will be sent by our doctor for either an x ray, ultrasound, CT Scan or an MRI. But WHY? And why are we sent for one, but not the others? Today's video titled 'What's the Difference Between X-ray, MRI, CT Scan and Ultrasound' will answer these two common questions.

Why is it important for YOU to know the DIFFERENCE between x-ray, MRI, CT Scan and MRI?
This knowledge will make you MORE INFORMED, and at one point in your life this information will be critical for either yourself or a loved one.
It can take weeks, months or even years to get some of these tests done, so it is critical that you know you are going for the correct one.
YOU are part of your healthcare team. This means you need to have a voice and contribute to your own health care. Being able to discuss these medical imaging tests with either your own or a family member's doctor is an enormous benefit. Nothing is worse than when a doctor is giving you results and you have no clue what they are talking about. After watching this video and reading the information below, you will NEVER be in the dark when it comes to discussing your health results.

The Difference Between X-Ray, MRI, CT Scan, Ultrasound

X-Ray
Uses X Ray RADIATION to take a 2D photograph of our BONES
Used to diagnose broken bones, fractures and dislocations
Relatively inexpensive, timely
HARMFUL to our body if we get too many
Required to be motionless during the test

CT Scan (Computed Tomography Scan)
Uses a higher dose of X Ray RADIATION to take photographed 'SLICES' of our BONEs
Used to diagnose smaller fractures or broken bones that a 2D X-ray fails to detect.
Used to observe below the surface of bony structures. Hence the 'slices'.
More expensive than X-Ray, and takes longer to get one
Required to be motionless during the test
Limit the number of these scans because of the HARMFUL higher dose of radiation

Ultrasound
Uses ultrasound waves to take either a 2D or 3D photograph of our bodily structures
SAFE for our body
Used to look at muscle, TENDON and LIGAMENT tears, strains and sprains. For example: Achilles tendon tear, ACL tear, rotator cuff tear, plantar fasciitis, tennis elbow.
Relatively inexpensive and timely
Can move your body part during the test

MRI (Magnetic Resonance Imaging)
Uses magnetic fields to take 'sliced' photographs
Similar to CT Scan but instead of radiation, an MRI uses magnetic fields
Used to look at the brain to diagnose conditions such as Parkinson's Disease, Multiple Sclerosis, Stroke, etc.
Used to look at the spinal cord and discs in our back to diagnose conditions such as cancer, disc herniation, stenosis.
High quality image
MRI machines have a small opening for our body part, which can trigger claustrophobia. Thankfully there is a sedative that can be given before the test is done to help us relax.
EXPENSIVE! MRIs can take months to years to get done!

The next time you are told to get an X-ray, MRI, CT Scan or Ultrasound you will know WHY you are being sent, which structures or tissues are being photographed, and most importantly you are now more informed which will help you advocate for a particular image or test the next time you believe you need one.
