MRI

MRI does not emit ionizing radiation like X-rays or CT scans. Instead, it uses a magnetic field and radio waves to create detailed images of the body's internal structures without exposing the patient to harmful radiation.

The iron in your blood is part of hemoglobin, which is a stable molecule and not affected by the magnetic field in an MRI. The iron atoms in hemoglobin are tightly bound within the molecule and not free to move, so they are not pulled out of the blood.

MRI uses short bursts of radio, at frequencies of a few tens to a few hundreds of Megahertz.

Exactly the same radiation that comes out of an ordinary TV transmitter, but in short bleeps,

and without any sound or picture modulation on it.

One application with properties similar to MRI is magnetic resonance spectroscopy (MRS), which also detects and analyzes the magnetic properties of atoms in the body to provide detailed information about tissue composition and metabolism.

Becuase the only thing an MRI doese is check for things that shouldn't be there in your brain. It's not a treatment option. That aside, most people don't have things that need to be scanned for or they just can't afford them, as sad as it is.

It means that a specific area on the left side of the brain is of concern and further investigation is needed through a magnetic resonance imaging (MRI) scan to better understand any abnormalities or potential issues in that area. An MRI can provide detailed images of the brain to help diagnose any potential conditions or concerns.

This means that the conus medullaris, the end of the spinal cord, is located at the level of the first and second lumbar vertebrae (L1-L2). It appearing unremarkable suggests there are no visible abnormalities or signs of compression or damage in this area.

This indicates that there is a bony growth (osteophyte) in the middle of the spine pressing on and changing the shape of the front part of the spinal cord. This can lead to symptoms such as pain, weakness, or numbness, and may require medical intervention to alleviate the pressure on the spinal cord.

This process is called magnetic resonance imaging (MRI). MRI uses a strong magnetic field and radio waves to create detailed images of tissues inside the body. The hydrogen atoms in our bodies align with the magnetic field, and when radio waves are sent through the body, these atoms emit signals that are used to create the images.

To create a synaptic map of a living human's brain, advanced imaging technologies such as electron microscopy combined with artificial intelligence algorithms would be necessary. These technologies would enable the high-resolution imaging and mapping of synaptic connections in real-time in a non-invasive manner. Additionally, the use of techniques like optogenetics to manipulate and understand the function of these synaptic connections could provide valuable insights into brain function and connectivity.

Diffuse disc osteophyte complex refers to the formation of bony growths and disc protrusions in the spine, which can cause compression on the thecal sac. Treatment usually involves a combination of therapies such as physical therapy, pain management, and in severe cases, surgery to alleviate pressure on the spinal nerves. Management focuses on relieving symptoms and preventing further damage to the spine.

When the vascular structures in the circle of Willis appear patent in MRI results, it means that there is normal blood flow through these arteries without any significant blockages or obstructions. This is a positive finding as it suggests good blood supply to the brain, reducing the risk of ischemic events like strokes.

Your question is impossible to answer. You didn't even mention what body part was being examined. Talk with your health care provider, who has access to your full history and physical, as well as knowledge of the location of your problem.

Chondral loss involving the posterior central aspect of the tibial plafond indicates damage to the cartilage at the back and center of the shinbone where it connects to the ankle joint. This can lead to pain, swelling, and limited range of motion in the ankle joint. Treatment may involve rest, physical therapy, and possibly surgery in severe cases.

This finding on brain MRI indicates the presence of small vessel disease, known as microangiopathy, which can lead to changes in white matter that appear as abnormal areas on T weighted images. These changes may be associated with risk factors such as hypertension, diabetes, or aging, and can lead to cognitive decline or vascular events like strokes. Further evaluation and management by a healthcare professional is usually recommended.

Complete effacement of the thecal sac refers to a condition where the space surrounding the spinal cord (thecal sac) is compressed or narrowed to the point where it is no longer visible on imaging studies such as MRI. This can be due to disc herniation, spinal stenosis, or other spinal abnormalities, and may result in symptoms such as pain, numbness, or weakness in the back or extremities. Treatment may involve conservative measures like physical therapy, medications, or in severe cases, surgical intervention.

When interpreting an imaging study (xray, CT, ultrasound, or MRI, among others), sometimes a particular finding can mean different things in different clinical situations. When a radiologist comes across a finding which may mean multiple things, a radiologist says "please correlate with clinical findings" or "clinical correlation requested" to indicate the finding may mean several things in different circumstances.

For example, on a chest Xray there may be some opacities in a lung field. That, combined with the clinical information that the patient has a high fever, with yellow sputum, high white blood cell count, and is a young woman without other medical problems--then the leading suspicion is that it is an infection, likely pneumonia. On the other hand, if the clinical information is that the patient has just had minor surgery, no fever, has some shallow breaths, then it's more likely that the opacities can be due to atelectasis.

From what I see in your question, you're talking about the bones in your neck called cervical bones. For the #'s you gave, it would mean there's narrowing or lack of a gap between cervical #5 thru cervical #7. (5-6-7) That's most of the way up from the base of the neck on the backside. Narrowing of spaces where there's usually gaps is caused by wear & tear and aging usually and when the cushions between the bones are shrinking from wearing down or the aging process the consequence is narrowing. In this case on the left sides of C5 thru C7.

yes! but it is MR conditional!! But not immediatly after the operation

I've heard that low frequencies can cause headaches. MRI's use low frequency in the process. It is possible this is the cause. I really do not know the answer. What I can say with absolute certainty is that following my MRI 2 days ago, I've had the WORST headache I've ever had in my life. I can finally understand what people with migraine must experience. UGH!! If you suffer from a headache following an MRI you are NOT crazy and you are NOT alone!!!

I recently had a lumbar spine MRI with and without contrast. My insurance company was charged $4,307 plus an additional $700+ for the radiologist's fee. When I saw the bill, I laughed thinking there must have been a mistake. Nevertheless, the insurance company actually approved $2,500 of the charges. I've had several other MRIs in the past which cost anywhere from $500 to $1750, including the radiologist's report. Since receiving the bill, I called some local imaging clinics whose charges range from $500 to $600 for a cash-pay lumbar spine MRI with and without contrast including the films and the radiologist's report.

My conclusion is there is no such thing as an 'average cost' for a lumbar spine MRI. The cost is whatever the clinic wants to charge. Unfortunately, the doctor who orders the MRI usually sends you to the MRI clinic associated with his practice and he has no idea of the cost. And the patient usually trusts the doctor and doesn't bother asking the price ahead of time or shopping around. That was what happened in my case, and now I know why insurance premiums are so high. The moral: always shop around...

Degenerative in medical terms means breakdown related to wear and tear.

Depending on how far they are from the scanner and the field strength, anything can be used. You generally don't want to use magnetic substances, because they can be pulled into the magnet and introduce large artifacts, but I've personally used steel screws in items used in the bore itself that could be dealt with because of the receive coil being used.

Any metal items can produce artifacts, however, if they are too close, so if you can stick with plastic, by all means do so (think sliding doors on plastic tracks rather than metal hinges and handles, or open faced shelves).

An EEG is for measuring the electrical activity of the brain and how it responds to stimuli. An MRI scan is more like an x-ray. It is for examining the physical structure of parts of the body. There is no saying which is more correct as they are measuring different things.

In an MRI, "multiple foci" refers to the presence of several distinct areas or lesions that can be observed within the scanned tissue. These foci may indicate various conditions, such as inflammation, infection, or demyelinating diseases like multiple sclerosis. The distribution and characteristics of these foci can provide important diagnostic information for healthcare providers.
