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.

A heterogeneous signal in the marrow on T1 and T2 sequences can be due to various reasons such as red marrow reconversion, inflammation, or underlying pathology. It is important to consult with your doctor or a radiologist for further evaluation and interpretation of the MRI findings to determine the cause and any potential concerns.

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.

Effacement of the anterior thecal sac refers to compression of the thecal sac in the spine due to conditions like disc herniation or spinal stenosis. This compression can lead to symptoms like pain, numbness, or weakness in the back or limbs. Treatment options may include physical therapy, medications, or surgery depending on the severity of the compression.

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.

Clinical correlation requested after an MRI means that the medical professional interpreting the MRI results is seeking additional information from the patient's symptoms, medical history, and other diagnostic tests to better understand the significance of the findings on the MRI scan. This helps in making a more accurate diagnosis and developing an appropriate treatment plan.

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.

Obtain a degree...Preferably a 4 year degree in Biomedical Equipment Technology, or BMET. Start out as a Biomed in a hospital working on basic medical instruments. Keep an eye out for an MRI posting, and apply. The Hospital will send you to OEM training. If the Hospital isn't your first choice, just go with an OEM such as Siemens or GE. They accept summer interns, if you are lucky you may get hired. I have been working for a hospital for 4 years.

does hyperintense means herniation dcis

no

It means that initially the radiologist saw a lesion at the spinal cord (at the last cervical vertebrae - C7), but when he looked to confirm it from another plane, it was not there so he concluded that it was an artifact. MRI artifacts are shadows, lesions, lines that appear on images but they don't have anatomical correspondence. Most of the are cause by blood flow, spinal fluid flow, patient movement, hardware problems, and many other reasons.

is a prescription reguired by law in Florida for a mri exam

an MRI machine is as tall as your tallest friend and as fat as your fattest friend. none of the sites i went on had the actual dimensions.
