Whiplash The Brain And Mri
Had whiplash accident then 9 months later on MRI had brain clots in brain/rare stroke. How is this possible. All kinds of nuerogical problems now too?
Traumatic dissection: Not uncommon, in certain violent accidents, to have damage to large blood vessels in neck, such as arterial dissection. This may happen in the back of neck to the vertebral arteries, which pass upwards inside a canal in the vertebral body called foramen transversarum. When neck violently moves, the blood vessel can be compressed or torqued, blocking blood flow and thus a stroke. ...Read more
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
Tingling left cheek, fingers and foot. Normal brain MRI & blood work. History of concussion & whip lash in past year. What should I do next?
Your symptoms: Are too vague and not anatomically connected. Concussion and whiplash have very little if anything to do with your complaints. If otherwise healthy, examine your social, family, work, and financial well-being. Correct what needs correcting before seeking a medical diagnosis. ...Read more
I was in an accident 3months ago had X-ray of my neck due to whiplash. I've been seeing a chiropractor but it still hurts. Should I get a mri?
Can a whiplash type accident cause C5 radiculopathy, and radiculitis at c7-8 I had an MRI done and it shows bulging discs?
I got whiplash in april from a rear end collision. Had xray and mri. Dr says everything is ok. but even after extensive physio my back and neck pain?
What other medical conditions?
How it was treatd from the start?
How the actual exam looks? ...Read more
Can a whiplash injury cause bone edema? I am being sent for an MRI following spinal x-ray, and am a little concerned. Whiplash injury 2 months ago, X-ray showed swelling and damage as well as bone oedema?
The : The cervical spine is made up of spinal vertebrae, disks, joints, muscles and ligaments. Spinal injury may damage these structures and cause swelling, tearing and breaking of these structures. This can be seen as edema (swelling) in bones. Edema is best seen on mri. Whiplash usually injures the soft tissues (muscles, ligaments, etc). Severe whiplash injuries may injure the bones and cause bone edema. ...Read more
Maybe safer in some: Gadolinium contrast could potentially cause kidney complications on rare occasion. Mri without contrast will reveal areas of atrophy, stroke, bleeding, tumors, hydrocephalus, etc, but will not clearly show certain ms lesions, aneurysms, avm's, some inflammatory problems, so, always discuss with your doctor as to why an ordered MRI might be done in a variety of ways. ...Read more
It depends: There are many types of brain tumors with variable appearances on a brain mri. Most appear as an abnormal mass of tissue often with edema (fluid/swelling) in the surrounding brain tissue. Many (but not all) tumors will enhance with contrast dye making them stand out against the normal non-enhancing brain tissue. ...Read more

Your dr. Needs to exam you, and place the need for imaging, such as a brain mri in appropriate clinical context. There are detailed criteria that are used in making this determination. You can view them on the website for the american college of radiology appropriateness criteria:

MRI risk: There are no substantiated cases of mris directly causing medical issues as a result of getting the study. The risk with getting MRI comes with those who have metal fragments in their body or have devices such as pacemakers that are incompatible with having a mri. The die used in mris can cause issues particularly in patients with renal problems. ...Read more
That depends: Basically to better evaluate the brain and orbits than you would see with a ct scan. Subtle findings are better seen with a mri- and it is frequently ordered after a negative ct scan. The combo 'brain and orbits' MRI is often ordered by physicians looking for signs of multiple sclerosis (I would ask your doctor why they ordered it). ...Read more
First MRI: Ask if the machine is 'closed' or 'open'. If you have difficulty in close spaces ask for an open machine. Ask what types of things you can bring with you. Metal that can be magnetized is not allowed. Ask about dental braces or metal orthopedic metal. If you are very nervous, ask about sedation. ...Read more
MRI finding: These are a very common finding. They can be the source of concern to patients when reading their MRI report. However, most doctors do not assign any significance to them unless there are a large number, or in the setting of multiple sclerosis. You can contact the doctor who ordered the MRI for more info, but suspect they will relay there is no reason for concern. ...Read more
Should be good: Open scanners have increased in popularity, they produce inferior scan quality because they operate at lower magnetic fields than closed scanners. However, newer 1.5 tesla open systems have become available, providing much better image quality than previous lower field strength open models. ...Read more
Yes, not always : Depends on the type of infection. A larger abscess will be detected. More diffuse infections such as meningitis may reveal characteristic suggestive of an infection. Usually need to combine clinical history, exam, blood tests, CSF analysis +/- ct/mri to make diagnosis of a brain infection. ...Read more
Think about it, Remy: Whatever would you do brain MRIs for if they didn't show "damage"? The difficulty here lies with your terminology. Brain "damage" is so vague as to be essentially meaningless. MANY disease processes can afflict the brain, & the MRI appearance of "damage" is distinctive depending on the kind of "damage" it is. Neuroradiologists interpret the "damage" all day long. I'm very grateful that they exist. ...Read more
Only if large enough: MRI with contrast has a resolution limit of about 5 mm, depending on the field strength of the magnet & the spin sequence performed (resolution of time-of-flight MRI or TOF-MRI is even worse). The "gold standard" for an aneurysm is a fluoroscopic angiogram of the brain, which only interventional neurologists or radiologists perform 4 (1) known stroke or (2) genetics. Use HealthTap Prime to discuss ...Read more
Lots of things: "Bright spots" on an MRI have various causes. They can range from benign, insignificant findings to infections, injuries, metabolic problems and more. An MRI is only a tool, and the findings need to be put in the context of the patient's clinical condition. Mris are often ordered unnecessarily and then odd findings (like bright spots) can make a straightforward case much more confusing. ...Read more
Tumor type: This depends on tumor type, size and location. If the type of tumor is not clearly obvious on mri, biopsy or removal may be needed. If it is small and clearly benign, it may be feasible to follow it over time wit homer imaging. You'll need to talk to your doctor for more information. ...Read more
A term typically used to describe a hyperextension injury to the neck, often associated with a motor vehicle accident. It is not unusual for patients who have sustained a whiplash injury to not show clear radiologic signs of trauma. Whiplash symptoms may come from an injury to the posterior facet ...Read more
