What Diseases Can An Mri Of The Brain Detect

How to Read an MRI of the Brain | First Look MRI

An MRI of the brain is nothing but images or slices of the brain that helps the doctor in assessing your brains conditions. There are many times when a doctor can recommend a an MRI of the brain to rule out the symptoms. MRI can help the doctor to make an early diagnosis and recommend a treatment plan for the patient.

Some diseases for which an MRI of the brain is needed are:

  • Inner ear or eye disorders
  • Blood clots
  • Bleeding in the brain or hemorrhage
  • Cysts
  • Abnormalities in development
  • Aneurysm

The MRI of the brain is not limited to these illnesses, its up to the doctor to recommend you diagnostic testing to identify the illness. Some other problems for which an MRI of the brain is required are for hearing loss, seizures, vision problems, muscle weakness, dizziness, behavior change, speaking difficulty, and so on. Since the brain is the hub of all information therefore, the MRI Elizabeth NJ clears the suspicion and helps the doctor in making a proper diagnosis.

Magnetic Resonance Imaging Uses Magnetic Fields And Radio Waves To Make A Picture Of The Brain No Radiation Is Used

Because a strong magnet is used, we must be very careful that metal objects do not enter the MRI scanner room.

For this reason, we ask that you wear comfortable clothes with no metal on them. Athletic apparel works great, but we also have scrubs without any metal on them for you to change into before entering the scanner room.

You will be asked to fill out a safety screening form to see if you have any implanted metal from a surgery.

Can I Get An Mri If I Have Implants

Yes. Titanium implants are MRI-compatible. Tell your doctor if you have any implants or prostheses, including hearing implants, a pacemaker, dental implants or vascular stents.

Inform your doctor of any non-titanium implants and check with the manufacturer of your device. Some non-titanium implants are still compatible with the machine and dont pose a risk during an MRI. If not, you and your doctor may need to decide on an alternative exam method.

What Are The Risks Of Mri

Pregnant women shouldnât get an MRI during their first trimester unless they absolutely need the test. The first trimester is when the baby’s organs develop. You also shouldn’t get contrast dye when youâre pregnant.

Don’t get contrast dye if you’ve had an allergic reaction to it in the past or you have severe kidney disease.

Certain people with metal inside their body can’t get this test, including those with:

  • Some clips used to treat brain aneurysms
  • Pacemakers and cardiac defibrillators
  • Certain metal coils placed in blood vessels

Let Your Doctor Know If You Have Claustrophobia

Preparation for MRI brain scan

For the duration of the MRI, you will be lying in an enclosed tube-shaped machine. While the length of time youll spend in there will vary, it could be as long as an hour. If youve ever dealt with claustrophobia, you may find this causes you a great deal of anxiety. To better cope with the process, talk to your doctor ahead of time and explain your concerns, as well as your history with claustrophobia. They may be able to prescribe a medication you can take before the procedure starts, which will help you stay calm during the MRI.X-ray

What To Expect During Your Scan

You can think of an MRI scanner as a big donut turned up on its side. As the person being scanned, you are like the jelly in the middle! Before your scan we will ask you or your parent several questions to ensure the MRI scan is appropriate for you. These questions ask about any types of metal that might be in or on your body. Once we decide the scan is right for you, we will give you a change of clothes and an opportunity to change in the bathroom. After changing, you can choose the movie you want to watch during the scan, and then you and a researcher will head into the scanning room. Here we will give you ear-plugs to block out the sounds of the scanner and a few extra sensors to monitor things like your breathing and heart rate. Once you are ready, you will lie down on a moving bed topped with cushions to make you comfortable. Then we will place a helmet over your head that will help us take pictures of your brain. Next, we will add headphones so you can listen to your movie while you are in the scanner, and cushions to keep your head comfortable and help you hold still. Finally, we will slowly move the table into position. Once we begin scanning, a researcher will check in with you every 5 minutes or so to see how you are doing. Of course, you can stop the scan whenever you would like.

The Science Behind An Mri Scan Is Hugely Complex

When going for an MRI Scan, the first thing to understand is that our bodies are made up mostly of water molecules . The machine uses the distinctive behavior of hydrogen atoms while within a magnetic field to build up a 2D or 3D image of the body part its scanning.

Doctors use the MRI scan for all sorts of diagnostic medicine, from detecting injuries such as spinal damage, to spotting tumors, to finding out whether medical treatment, such as chemotherapy, has been successful.

What Should You Not Do Before An Mri

Just like any other diagnostic testing, there are some things that you will need to do to prepare for an MRI. The good news is that in most cases, MRIs require very minimal preparation.

Unless your doctor tells you not to, you should be able to eat and drink normally on the day of the MRI. You should also be able to take your medications as normal.

With 40 million annual MRI scans in the U.S., prep instructions can vary.

Maybe Not Eat or Drink

In some cases, you may be asked not to eat or drink before having the MRI scan done. According to the NHS, you may have to abstain from eating and drinking for as long as four hours before the test. However, this is not always necessary, and it will depend on what part of your body is being tested and what your doctor is looking for.

Maybe Limit Your Bathroom Trips

Another factor that can vary is that you may have to drink a large quantity of water before your MRI. In this case, you may also have to limit your trips to the bathroom so that the water is still present before testing.

Always Listen to Your Preparation Instructions

Most importantly, remember that your instructions will vary slightly depending on the test location and goals. As such, you should always follow the specific instructions that you receive. The previous points may or may not be included in your instructions.

Regardless of your situation, it would be best if you always kept the following preparations in mind:

What To Expect During The Mri

Once youve been prepped for the scan, youll be brought to the MRI machine. The machine looks like a long metal tube with a table that slides out from inside. The table is where you lay and it will slide back into the tube where the scan will take place. If youre feeling nervous, dont be embarrassed. Its common to feel uneasy, especially when its your first time but you can do it and you will make it through!

During the scan, youll have to lie very still. That said the tech may ask you to perform small movements or ask you simple questions but wait for their instructions. Its also worth noting, MRI machines are noisy. Typical sounds are pulsing and loud thumping noises. Dont be alarmed, this is normal. If you think this may alarm you, you can ask your tech if they can provide a pair of headphones ahead of the procedure to decrease the noise.

What Kind Of Equipment Is Used In An Mri

A typical MRI machine is a large tube with a hole at both ends. A magnet surrounds the tube. You lie on a table that slides all the way into the tube.

In a short-bore system, you are not totally inside the MRI machine. Only the part of your body that’s being scanned is inside. The rest of your body is outside the machine.

An open MRI is open on all sides. This type of machine may be best if you have claustrophobia — a fear of tight spaces — or you’re very overweight. The quality of images from some open MRI machines isn’t as good as it is with a closed MRI.

Inform Your Doctor Of Your Medical History

The first step in preparing for an MRI is to be upfront and honest with your doctor. Inform them of your medical history because some conditions may require a few modifications to the procedure.

The scan is essentially a giant magnet which can pose some problems especially if you have metal implants. Things like a pacemaker, implanted drug infusion devices, and cochlear implants may cause some problems. But rest assured, your doctor will run through an extensive list of conditions to ensure its safe to perform the MRI.

How Should You Prepare For An Mri

Itâs a good idea to fully understand the reasons for the MRI. You can start by asking your doctor questions like:

  • Why do I need an MRI?
  • Is an MRI the best way to check on my condition?
  • How will the results affect my treatment?
  • What are the risks?
  • Do the benefits of this test outweigh the risks to me?

Before your MRI, let your doctor know if you:

  • Have any health problems, such as kidney or liver disease
  • Recently had surgery
  • Have any allergies to food or medicine, or if you have asthma
  • Are pregnant, or might be pregnant

No metal is allowed in the MRI room, because the magnetic field in the machine can attract metal. Tell your doctor whether you have any metal-based devices that might cause problems during the test. These can include:

  • Watch
  • Wig

If you don’t like enclosed spaces or you’re nervous about the test, tell your doctor. You may be able to have an open MRI or get medicine to relax you before the test.

What Does An Mri Of The Brain Show

By looking at MRI images, your doctor can see details of blood flow and fluids surrounding the brain, which can help determine abnormalities in the brain relating to arteries and veins.

An MRI brain scan also shows brain lesions. A brain lesion appears as a dark or light spot that does not look like normal brain tissues. Brain lesions may be present due to multiple sclerosis or as a result of an infection or a tumor.

In general, a brain MRI will enable your doctor to examine blood flow and tissue health in the following brain structures.

  • Cerebrum: The cerebrum is the front part of the brain that involves movement, body temperature, touch, vision, hearing, reasoning, emotions and learning.
  • Brainstem: The brainstem is the middle of the brain. This region involves eye and mouth movement, sensory messages, hunger, consciousness, cardiac function and involuntary muscle movements.
  • Cerebellum: The cerebellum is the back of the brain which coordinates voluntary muscle movements and helps you maintain posture and balance.

Overall, an MRI will give your doctor a clear and complete view of your bodys most complex organ.

Can I Wear A Wig

No. Some wigs contain trace amounts of metal from wig clips, hairpins or adjustable straps. Many types of extensions also contain metallic particles. The MRIs powerful magnetic field causes metal objects and particles to heat up, which can lead to burns.

Be aware that products like hairspray can interact with the MRI, as well. Even if you avoid burns, the resulting images could come out blurry from the presence of metal which means you may have to redo the scan.

Remove Metal Objects And Change

You will be asked to remove any metal piercings or jewellery. Metal interacts with the MRI machine and will result in distorted images. Some clinics will allow you to wear your loose-fitting clothing. This is as long as the clothes provide access to the area being scanned and do not contain any metal fasteners. Some clinics will have you change into a hospital gown to ensure there is no clothing interference with the machine.

Watching For Allergic Reactions

Magnetic Resonance Imaging (MRI)

Its uncommon for patients to have allergic reactions to the contrast dye, but it isnt impossible. If your doctors used this dye for your MRI, be sure to watch for the signs of an allergic reaction in the hours following your procedure. Just a few of the symptoms to watch for include:

  • Hives
  • Itchiness
  • Shortness of breath

If you experience any of these symptoms, call your doctor or the imaging center where you had your MRI and report your concerns. If the reaction is severe, dont hesitate to head to an emergency room for treatment.

Tips On How To Prepare For An Mri Scan

Preparing for any medical test can be anxiety-provoking, especially when its your first time experiencing it. Not knowing what to expect during the procedure plus the uncertainty of the results is a lot to think about.

To help ease your mind, you should first know that a magnetic resonance imaging scan is a non-invasive medical procedure. Its an important imaging technique that allows your doctor to examine your organs, tissues, and skeletal system and is used to help diagnose many different medical conditions. To help ease your worries and to help you prepare for your upcoming scan, well provide you with tips on how to prepare as well as break down what you can expect before, during, and after the procedure. Lets get into it.

What Is A Magnetic Resonance Imaging Scan

Magnetic resonance imaging is a non-invasive radiographic study used to diagnose medical problems. Much like an x-ray, the technique allows the visualization of structures that would otherwise be inaccessible without surgery.

This is accomplished with the use of a large magnet, rather than X-ray radiation, while the patient lies on a table. The pulse of the magnet affects the water molecules of the body and the resulting changes can produce images. MRI is especially helpful in specific areas of the body, including the brain.

An MRI may be ordered if your healthcare provider suspects that there is a structural abnormality that may be causing your symptoms.

For instance, some individuals may have central sleep apnea because of a stroke. Alternatively, seizures that occur during sleep may prompt an MRI of the brain to investigate the cause of epilepsy.

If Youre Claustrophobic Inform Your Doctor

If you dont know already, during an MRI you are placed inside an enclosed tube-shaped machine. The duration of the scan will vary from person to person but in some cases, it can last up to an hour. While this is no problem for some people, those who are claustrophobic may feel very uncomfortable.

If you are claustrophobic or are concerned about being in the machine, be sure to inform your doctor. Your doctor may be able to help calm your nerves or provide you with medication to help keep you calm during the procedure.

How The Test Will Feel

Head MRI: Purpose, Preparation, and Procedure

If you need dye, you will feel the needle pinch in your arm when the dye is injected into the vein.

An MRI exam causes no pain. If you have difficulty lying still or are very nervous, you may be given a medicine to relax. Too much movement can blur the images and cause errors.

The table may be hard or cold, but you can ask for a blanket or pillow. The machine makes loud thumping and humming noises when turned on. You can ask for ear plugs to help reduce the noise.

An intercom in the room allows you to speak to someone at any time. Some MRIs have televisions and special headphones that can help you pass the time or block the scanner noise.

There is no recovery time, unless you were given a medicine to relax. After an MRI scan, you can go back to your normal diet, activity, and medicines.

How Do Doctors Use Mris

An MRI helps a doctor diagnose a disease or injury, and it can monitor how well youâre doing with a treatment. MRIs can be done on different parts of your body. It’s especially useful for looking at soft tissues and the nervous system.

An MRI of the brain and spinal cord can help find many things, including:

  • Blood vessel damage, including an aneurysm
  • Brain injury
  • Prostate
  • A special kind of MRI called a functional MRI maps brain activity.

    This test looks at blood flow in your brain to see which areas become active when you do certain tasks. An fMRI can detect brain problems, such as the effects of a stroke, Alzheimerâs, or a brain injury. It can also be used for brain mapping if you need brain surgery for epilepsy or tumors. Your doctor can use this test to plan your treatment.
