Understanding Magnetic Resonance Imaging
MRI is a tool doctors use. It lets them look inside the body. They don't need surgery.
Related glossary terms: X-Ray Imaging, Disc Herniation, Spinal Adjustment.
MRI makes a strong magnetic field. This field lines up tiny parts in your cells. Then, radio waves go through your body.
These tiny parts send back signals. A computer turns them into clear pictures. The pictures show bones, muscles. And organs.
MRI is great for soft tissues. It shows the brain, spine. And joints well. Other tests can't do this.
If someone hurts their back, MRI can help. It shows if a disc is hurt. It can also show if a nerve is pinched.
X-rays mostly show bones. MRI shows more. It gives a full picture of what's inside.
This makes MRI key for many problems. It helps with sports injuries. It also helps with diseases like MS (multiple sclerosis).
How Magnetic Resonance Imaging Works?
The MRI machine is a big tube. You lie inside it. The machine makes a very strong magnet.
The magnet is 1,000 times stronger than a fridge magnet. It changes how tiny parts in your body act. These parts are called hydrogen atoms.
Radio waves go through your body. The atoms send out signals. A computer uses these to make pictures.
It makes pictures slice by slice. Think of a loaf of bread. Each slice is a new picture.
The test doesn't hurt. But it can be loud. You'll hear knocking or buzzing sounds.
You must lie still. This can take 20 to 60 minutes. If you move, the pictures won't be clear.
Some people feel scared inside the tube. Doctors can give medicine to help. This medicine helps you relax.
You must take off metal things. The magnet can pull them hard. This includes jewelry or keys.
MRI centers ask you to fill out forms. These forms check for safety. They make sure you can have the scan.
There are different MRI scans. Some use a special dye. This dye makes some areas show up better.
The dye is called contrast. It goes into your body. It can highlight blood vessels or tumors.
Other scans focus on one body part. They can look at the brain, spine. Or knee. The scan type depends on what the doctor needs.
Why Magnetic Resonance Imaging Matters?
MRI helps doctors find problems. Other tests might miss these. This helps them make better choices.
An X-ray can show a broken bone. But it can't show a torn ligament. MRI can show this.
MRI can also show a herniated disc. This helps doctors decide on treatment. They can choose surgery, therapy. Or medicine.
Early and right diagnosis helps. It leads to faster recovery. It also means fewer problems later.
MRI is safer than some tests. It doesn't use radiation. This is good for kids and pregnant women.
It's also good for people who need many scans. But MRI isn't for everyone. Some people can't have it.
People with metal implants can't usually have MRI. The magnet can cause trouble. This includes pacemakers or hearing implants.
In these cases, doctors pick other tests. They might choose a CT scan. Or they might use ultrasound.
When Magnetic Resonance Imaging Matters Most?
Doctors often use MRI for pain. It helps if pain doesn't go away. It also helps with weakness or other symptoms.
If back pain lasts for weeks, MRI can help. It can find the cause. This might be a herniated disc or arthritis.
MRI checks for serious problems too. It can find tumors, strokes. Or infections. Athletes use it for sports injuries.
It can show torn ligaments. It can also show muscle damage. This helps athletes get the right treatment.
MRI is important in emergencies. It can show bleeding in the brain. It can also show a stroke.
Quick diagnosis can save lives. But MRI isn't always the first test. It costs more and takes longer.
Doctors usually start with simpler tests. They might use X-rays or ultrasound first. They use MRI when they need more detail.
For people in Hermitage, TN, MRI helps chiropractors. Chiropractors treat back, neck. And joint pain. MRI shows what's causing the pain.
It can show a disc problem. It can also show a pinched nerve. This helps chiropractors make a treatment plan.
The plan might include adjustments. It might also include therapy. Or it might mean seeing another specialist.
