What Does An Mri Head Scan Detect

How Brain MRI can Help Diagnose Alzheimers Disease
  • Stroke: occurs when a blood vessel is blocked or bleeding into the brain. Signs include severe headaches that come on suddenly, weakness, impaired vision, confusion, trouble speaking, and dizziness and imbalance. Because of their high resolution, MRI scans are used for brain aneurysm diagnosis and spotting weak areas of the arteries that can lead to stroke
  • Damage and Abnormalities: MRI scans can also detect changes to the structure of the brain such as birth defects, cerebral palsy, developmental deformities, and severe brain damage caused by trauma.
  • Cysts and Tumors: MRI scans are used for brain tumor diagnosis and the detection of small cysts that would not be picked up by a CT scan. Doctors may inject a special dye into the brain just before the head scan to help get a clear picture of the different areas of brain tissue. This image helps them find hidden tumors and cysts that are nearly impossible to identify by any other method.
  • Headaches that feel very different from those that you usually experience could be a warning sign of something more serious. Diagnostic imaging centers can perform the high tech head scan essential for early detection that could save your life.

    When To Get An Mri In Atlanta

    If you begin experiencing symptoms of a TBI, you should seek out a doctor who can perform an MRI in Atlanta as soon as possible. When left untreated, these injuries can cause long-term damage and increase the likelihood of future degenerative disorders. However, if you have been in a car accident, you are already at risk for a brain injury and should undergo an MRI before symptoms have the chance to appear.

    Early detection of brain injuries can lead to substantially shorter recoveries and improved outcomes. Before you or your doctor would notice a problem, an MRI can identify the brain injury in the critical first 48 hours after it has been sustained and begin making a plan from there. The more time that elapses between sustaining and treating the brain injury, the more likely you are to suffer from secondary injuries that result from the initial trauma.

    When you come to AICA Orthopedics for your brain imaging, we are able to provide not only expertise in car accident injuries, but a comprehensive plan of care. Our radiologists will perform your MRI in Atlanta while our staff of expert doctors and chiropractors evaluate the results and develop a course of treatment. AICA Orthopedics sees car accident victims daily and can help determine the severity of an injury and guide you towards the most effective recovery. today!

    Why An Mri Is The Way To Go

    Whenever theres reason to believe you could have a swelling in the brain, a tumor, or something like multiple sclerosis, its best to schedule an MRI scan as soon as possible. Why? Because an MRI scan has the power to produce more accurate and more detailed images than a CT scan, X-ray, or even an ultrasound.

    A CT scan relies on X-rays, while MRI scans utilize powerful radio waves. This means that MRI machines can provide you and your doctor with a lot more information comparatively. You should know that just because MRI scans are more powerful and more revealing does not mean that they are more harmful than an X-ray. MRI machines dont emit the same amount of radiation as a CAT scan or an X-ray.

    Why Did My Doctor Order An Mri With Contrast

    The contrast is a chemical that helps show the condition of your organs and blood vessels very clearly more clearly than with an MRI alone. The quality of the MRI images is enhanced significantly with contrast.

    Youll be given an IV to administer the contrast. It takes less than half a minute for the dye to flow into your blood vessels. After the test, the substance is eliminated from your body via your urine within one day.

    Following are four categories of physical problems that can be illuminated with use of an MRI with contrast.

    Why Choose An Mri

    A brain scan to tell if you

    While you will discuss symptoms with your doctor as a part of your diagnosis, one of the best ways to determine prognostic information for a brain injury is to perform an MRI, or magnetic resonance imaging. This procedure allows doctors to receive a clear image of the brain and locate any potential damage with precision. This visualization can also help with determining the severity of the damage.

    CT scans used to be more commonly used to identify brain injuries than MRIs or other counterparts. However, in the past, most MRIs in Atlanta were only able to identify severe damage to brain tissue. But as more recent versions of the technology become available, doctors are better able to see mild injuries and concussions when using MRIs. These new techniques can show more in-depth brain structure and measurements of brain function that allow doctors to detect changes as a result of these injuries. As these abilities have emerged, MRI has become the scan of choice for identifying TBIs.

    Another benefit of MRIs is that they do not involve exposure to radiation like CT scans or x-rays. While an MRI often lasts from thirty to ninety minutes, the extended period of time is safer due to a lack of exposure. MRIs also do not typically require any medication to be administered, so you can go about your day once it has been completed.

    What Is The Difference Between A Head Mri And A Brain Mri

    A head MRI and a brain MRI are the same procedure. They both provide images of the inside of your head. While healthcare providers most often use head and brain MRIs to assess your brain, these imaging procedures provide images of other structures in your head, too, such as facial bones, blood vessels and nerves.

    What Does The Equipment Look Like

    The traditional MRI unit is a large cylinder-shaped tube surrounded by a circular magnet. You will lie on a table that slides into a tunnel towards the center of the magnet.

    Some MRI units, called short-bore systems, are designed so that the magnet does not completely surround you. Some newer MRI machines have a larger diameter bore, which can be more comfortable for larger patients or those with claustrophobia. “Open” MRI units are open on the sides. They are especially helpful for examining larger patients or those with claustrophobia. Open MRI units can provide high quality images for many types of exams. Open MRI may not be used for certain exams. For more information, consult your radiologist.

    What Is Magnetic Resonance Imaging

    Magnetic resonance imaging is a diagnostic procedure that uses acombination of a large magnet, radiofrequencies, and a computer to producedetailed images of organs and structures within the body. UnlikeX-raysorcomputed tomography, MRI does not use ionizing radiation. Some MRI machines looklike narrow tunnels, while others are more spacious or wider. MRI scans canlast from 30 minutes to two hours.

    What Should I Expect During A Brain Mri

    How Does an MRI Detect a Brain Injury?

    Most brain MRI exams are painless, but some people find it uncomfortable to remain still for 30 minutes or longer. Others may experience anxiety due to the closed-in space while in the MRI machine. The machine can also be noisy.

    The general steps of a brain MRI scan and what to expect include:

    In some cases, your MRI may require contrast. If this applies to you, your healthcare provider will give you an IV injection of contrast material before you undergo the MRI. The IV needle may cause some discomfort but this wont last long. You may have some bruising afterward. Some people experience a temporary metallic taste in their mouth after the contrast injection.

    If you have claustrophobia, your healthcare provider may recommend a sedative drug so you feel more relaxed during the exam, or even anesthesia.

    During the exam, its important to stay still to obtain the clearest images. Children who have difficulty staying still may need sedation, administered either orally or through an IV line. Sedation can also be helpful for adults who are claustrophobic.

    You will lie down on a table that slides into the MRI machine. The table slides through a large magnet shaped like a tube. You may have a plastic coil placed around your head. After the table slides into the machine, a technician will take several pictures of your brain, each of which will take a few minutes. There will be a microphone in the machine that allows you to communicate with staff.

    The test normally takes 30 to 60 minutes. You may receive a contrast solution, usually gadolinium, through an IV to allow the MRI machine to see certain parts of your brain more easily, particularly your blood vessels. The MRI scanner will make loud banging noises during the procedure. You may be offered earplugs to block the MRI machines noises, or you may listen to music during the test.

    There are no risks associated with an MRI itself. There is a very slight chance that you will have an allergic reaction to a contrast solution. Tell the medical staff if you have decreased kidney function. It may not be safe to use contrast solution if this is the case.

    How To Prepare For The Test

    You may be asked not to eat or drink anything for 4 to 6 hours before the scan.

    Tell your health care provider if you are afraid of close spaces . You may receive medicine to help you feel sleepy and less anxious. Or your provider may suggest an “open” MRI, in which the machine is not as close to the body.

    You may be asked to wear a hospital gown or clothing without metal ties . Certain types of metal can cause blurry images.

    Before the test, tell your provider if you have:

    • Brain aneurysm clips

    A blow to the head can be scary. Usually, the injury is not severe. But sometimes there can be a concussion, bleeding on the brain, or cracks to the skull.

    It is important for the doctor to examine you or your child for a possible concussion or another injury. A blow to the head can cause a brain injury.

    The doctor may order a brain scan to make sure you do not have a fractured skull or a serious brain injury. But these scans are usually not needed. Heres why:

    Brain scans are usually not helpful for a concussion.

    A CT scan takes pictures to create images of the brain. The scan can show if theres a fracture or bleeding. An MRI creates clear images of brain tissue.

    But these scans cannot show if you have a concussion. A concussion is different from a fracture or bleeding. A concussion affects how your brain works, and most people recover within a few weeks.

    How do you know if you have a concussion?

    Only a doctor can diagnose a concussion. The doctor will:

    • Ask about your accident.
    • Check your memory, speech, balance, and coordination.
    • Check your head, eyes, ears, and neck.
    • Look for symptoms of a concussion:
    • Headache, vomiting, nausea
    • Confusion, memory loss, poor concentration
    • Sensitivity to light or noise
    • Brief loss of consciousness

    Scans have risks.

    Brain scans cost a lot.

    A standard brain CT scan costs hundreds of dollars, and an MRI scan costs even more. If your results are not clear, you may have to pay for extra tests and doctor visits.

    Non-contrast MRIs are especially recommended for pregnant women and kidney function compromised patients who cant typically use contrast MRI medical imaging.

    Pregnant women are generally advised to take non-contrast MRIs unless their physician says otherwise. This is because gadolinium dye is associated with increased risks to the fetus.

    So, your medical caregiver should only suggest you take a contrast MRI during your pregnancy if its expected to improve the fetal and maternal outcome .

    Generally, non-contrast imaging is popular with most orthopedic studies, since the imaging comes out clear without the contrast dye.

    What Happens During An Mri

    MRI may be performed on an outpatient basis or as part of your stay ina hospital. Procedures may vary depending on your condition and yourdoctor’s practices.

    Generally, MRI follows this process:

  • You will be asked to remove any clothing, jewelry, eyeglasses, hearing aids, hairpins, removable dental work, or other objects that may interfere with the procedure.

  • If you are asked to remove clothing, you will be given a gown to wear.

  • If you are to have a procedure done with contrast, an intravenous line will be started in the hand or arm for injection of the contrast dye.

  • You will lie on a scan table that slides into a large circular opening of the scanning machine. Pillows and straps may be used to prevent movement during the procedure.

  • The technologist will be in another room where the scanner controls are located. However, you will be in constant sight of the technologist through a window. Speakers inside the scanner will enable the technologist to communicate with and hear you. You will have a call button so that you can let the technologist know if you have any problems during the procedure. The technologist will be watching you at all times and will be in constant communication.

  • You will be given earplugs or a headset to wear to help block out the noise from the scanner. Some headsets may provide music for you to listen to.

  • During the scanning process, a clicking noise will sound as the magnetic field is created and pulses of radio waves are sent from the scanner.

  • Computed Tomography Brain Scan

    A CT scan or CAT scan, which stands for computed tomography, can detect bleeding, swelling, and skull fractures. CT uses X-ray data and a computer to generate 3D images of structures. Brain CT scans help surgeons decide if a brain injury, stroke, or herniation requires immediate surgery.

    CT scans are safe for most people. However, because CT scans expose you to ionizing radiation, they may increase your lifetime cancer risk slightly. As with all tests, its best to weigh the risks and benefits.

    Magnetic Resonance Imaging Brain Scan

    MRIs are often located in radiology centers or hospitals. MRIs work by aligning the hydrogen molecules in your cells using powerful magnets. As the molecules absorb the energy from the radiofrequency waves, they emit a signal in response. With software help, the data becomes a detailed image. Bodily structures with high water content, like the soft tissues and organs such as the brain and kidneys, create the most contrast and therefore produce better MRI images.

    Because MRI machines use strong magnetic fields, this type of medical imaging isnt right for everyone. Let your provider know if you have any implanted medical devices and surgical hardware , dental implants, metal foreign bodies, tattoos, and permanent make-up.

    If you are claustrophobic, let your health provider know. You may also inquire about using an open-MRI which, as its name suggests, is open on at least three sides. With no tunnel to fit into, open MRI scanners can accommodate more body types.

    A major drawback of open MRIs is poor image quality. Because of its open-air design, the scanner loses some of its magnet strength. Instead of an open MRI, Ezra uses 3T MRI scanners at all of their partner facilities. These scanners feature a larger bore with a shorter tunnel, a stronger magnet, and faster scan times.

    Reaction To The Study

    How MRI Can Help Diagnose and Track Multiple Sclerosis

    Healthline asked Rebecca Edelmayer, Ph.D. to weigh in on the research. She is a scientist and senior director of scientific engagement for the Alzheimers Association.

    This research is in its early days and it is not ready to be used as a stand alone diagnostic tool, she told Healthline.

    It is a model that will need more testing in a larger prospectively collected set of data from a diverse group of individuals, Edelmayer added. For the model to be effective at predicting Alzheimers and other dementia, it will need to be generalizable to the broader Alzheimers population.

    Edenmayer also noted that the diagnostic model was developed for a specific type of MRI machine with a particular strength of magnetic field.

    She said with a variety of machines in use, the results cant be generalized to all types of scanners. But she said the research is working to address an important issue in the field early detection.

    With FDA accelerated approval of the first anti-amyloid disease-modifying Alzheimers treatment and more coming down the pipeline, it is vital that individuals with Alzheimers be diagnosed early in the disease process when treatment may be most beneficial, she explained. Plus, early detection of Alzheimers allows individuals and their families more time to plan for the future, participate in clinical trials and seek community resources.

    How Do I Prepare For A Brain Mri

    Guidelines about eating and drinking before a brain MRI vary based on the reason for your MRI. Eat and take your medications as usual unless your healthcare provider tells you otherwise.

    The magnetic resonance imaging scanner uses strong magnets and radio wave signals that can cause heating or possible movement of some metal objects in your head and/or body. This could result in health and safety issues. It could also cause some implanted electronic medical devices to malfunction.

    If you have metal-containing objects or implanted medical devices in your body, your healthcare provider needs to know about them before your brain MRI. Certain implanted objects may require additional scheduling arrangements and special instructions. Other items dont require special instructions but may require an X-ray to check on the exact location of the object before your exam.

    Its important to tell your healthcare provider and MRI technologist if you have any of the following:

    • Cardiac pacemaker.

    Leave all jewelry and other accessories at home or remove them before your brain MRI. Metal and electronic items arent allowed in the exam room because they can interfere with the magnetic field of the MRI unit, cause burns or become harmful projectiles. These items include:
