When it comes to medical imaging, few tools get more widespread use than X-rays and MRIs. Although both accomplish the same end goal (helping physicians to see what’s happening inside your body), the two are distinct when it comes to how they work, what they pick up on and when they’re utilized.
If you’ve ever been confused about whether you should get an X-ray or an M.R.I., this article is for you — and for your many, many confused fellows.
What Is an X-ray?
An X-ray is a quick and painless imaging test — one of the oldest and most common imaging procedures — that quickly produces images of the inside of your body. Its most popular uses include:
- Broken bones
- Lung infections such as pneumonia
- Tooth issues
- Joint dislocations
X-ray images are typically black and white, with bones appearing in a clear white and softer tissues lighter or less defined.
Urgent care x rays services frequently include X-rays, which are quick and effective for diagnosing injuries such as fractures or sprains.
What Is an MRI?
MRI is an acronym for Magnetic Resonance Imaging. It relies on powerful magnets and radio waves to generate detailed images of organs, muscles, nerves and other soft tissues inside the body. MRIs are ideal for examining:
- Brain and spinal cord
- Muscles and ligaments
- Internal organs
- Tumors or cysts
MRIs don’t use radiation, as X-rays do. They do not, however, provide radiation like traditional X-rays do; instead, they employ a series of magnetic fields to create cross-sectional images from various angles.
Differences Between X-rays and MRIs
Type of Imaging
- Dense materials, such as bones, appear on X-rays.
- MRIs provide a high level of detail of soft tissues.
Speed
- X-rays require only a few minutes.
- An MRI can last 30 minutes to an hour or even longer.
Radiation
- X-rays involve a low dose of radiation.
- MRIs use no radiation at all.
Cost
- X-rays tend to be cheaper.
- MRIs cost more because of the machinery and time.
Comfort
- Decide whether or not to include: Are cooler think before you go hunting styles are available nowadays neat.
- MRIs mean lying still on a narrow table within a tube, which can be uncomfortable for claustrophobic people.
When Should You Get an X-ray?
When to have one An X-ray is typically the first imaging test a physician will order when you:
- A suspected broken bone
- Chronic cough or tightness in chest
- Joint pain or swelling
- Some recent fall or injury

When Might an MRI Be the Better Option?
It is usually a doctor who orders the M.R.I. when he or she needs a better view of soft tissue, and when other imaging tests didn’t yield enough information. You probably need a MRI if:
- Ongoing back or neck pain
- Unexplained headaches
- Weight, with muscle or sports strains.
- Sensation such as numbness or tingling in the extremities
MRIs are also generally accepted for tracking chronic diseases like multiple sclerosis or some forms of cancer.
Safety and Risks
- Both imaging tests are low-risk, however, they require special precautions.
- Because X-rays are a form of radiation, they’re used judiciously, especially for children and pregnant women.
- MRIs are generally safe for most people; they can be dangerous for those with metal implants, or pacemakers, and for those who experience claustrophobia.
Be sure to let your health care provider know if you have conditions or implants that could create a problem before undergoing either test.
Which One Do You Need?
Which You Might Need Whether you’ll get an X-ray versus an MRI depends on the nature of your symptoms and what your doctor is looking to diagnose. Sometimes your doctor may even order both tests to get a better picture.

FAQs
Q1: What is the main difference between an X-ray and an MRI?
A: X-rays use radiation to capture images of dense structures like bones, while MRIs use magnetic fields and radio waves to produce detailed images of soft tissues like muscles and organs.
Q2: Is an MRI safer than an X-ray?
A: MRIs don’t use radiation, making them safer for frequent use. X-rays involve low radiation exposure and are generally safe but used more cautiously for children and pregnant women.
Q3: When should I get an X-ray instead of an MRI?
A: An X-ray is typically used for diagnosing broken bones, lung infections, or joint dislocations. It’s quicker and more cost-effective for initial evaluations of injuries.
Q4: What conditions require an MRI?
A: MRIs are used to diagnose soft tissue conditions like brain issues, ligament tears, spinal cord problems, or unexplained chronic pain when more detail is needed.
Q5: How long does each test take?
A: X-rays take just a few minutes. MRIs can take 30 minutes to over an hour, depending on the area being examined.
