Mri Brain Wwo Contrast
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
Stimulants: Stimulants such as Cocaine and amphetamine exert their effects on the user's nervous system and change the user's emotions, behavior, and affects cognition. They may cause miicrovascular ischemic disease of the brain which is unlikely to be detected by MRI or ct scan. ...Read moreSee 1 more doctor answer
No: Imaging studies do not show "everything". For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine. ...Read more
NO: Mri is an imaging device that is independent of function. Think of your car mechanic and a problem with your car. Lifting the hood and looking is like getting an mri. A good mechanic will want to turn it on and drive around and think carefully about what may be wrong. A good brain mechanic will ask appropriate questions and get appropriate tests and think about what may be wrong. ...Read more
CT angiogram: A regular ct scan might detect a large aneurysm with calcium. A test that is designed specifically to look for aneurysms is the ct angiogram. With this test contrast goes into the vessels of the brain. If there is an aneurysm that is larger than 2 mm, it should be detected with this technique. ...Read more
Very little chance: Because our understanding of radiation induced cancer is incomplete, it is assumed that any exposure to radiation increases the risk of developing cancer. This is called the non-threshold model. According to a recent nejm article the risk is approximately 0.005% at age 35 that a single ct brain would cause death due to cancer. N engl j med 2007; 357:2277-2284. The risk is even smaller at > age. ...Read more
Not likely: Most intracranial vascular anomalies, including aneurysms, require IV contrast to be seen on ct head. However, ct without contrast is 90% sensitive for intracranial bleeding. The risks of IV contrast for ct include kidney injury and allergy to contrast dye. Good luck! ...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
Nope: Sometimes you can see evedence of bleeding. With traumatic brain injury sufficient to cause changes on ct typically survival is markedly reduced. Certain types of MRI done at the right time following a brain injury can sometimes show evidence of cerebral contusion. Much of the damage done with traumatic brain injury is microscopic (too small even with diffuse axonal injury) to be seen on mri. ...Read more
Need contrast: Very difficult to see aneurysms in the brain without contrast. If you are concerned about this as a possibility you should ask your doctor about your risk. ...Read more
Possibly: But not definitively! needs contrast to better define the location and extent. ...Read more
Mri brain w &w/o contrast unremarkable except for r mastoiditis which was unchanged. Last MRI 6 months prior. Doc has never addressed it. Is this ok?
What does scattered small foci of t2 hyperintensity in the subcortical white matter means. this is from my mri brain w/o contrast test results?
These: are usually due to age-related microvascular changes, and are common incidental MRI findings as we age. However, there are other potential less-likely causes, so you should talk to your doctor about the significance of this finding in your particular case. ...Read moreSee 1 more doctor answer
Hello..Could you plz explain the findings of an MRI brain & orbits (plain & post contrast) that I just did. It said multiple small oval area of high SI on flair & T2 WI is seen at the juxta-cortical white matter, U fibers and corona radiata of both cerebr
You need a: Radiologist on HealthTap to explain these findings. I don't think anyone else will be able to do so. ...Read more
Is it possible to have a normal MRI of brain (without contrast), but still have a clot or clots in small/medium blood vessels of brain?
POSSIBLE: Depending on resolution of mri, and thickness of cuts, is possible to miss small stroke, and not visualize minimal pathology, but a clinical exam by a neurologist should be able to correlate a potential stroke if exam is consistent, regardless. In some cases, a followup image is useful. ...Read moreSee 1 more doctor answer
A day after MRI of brain and spine w contrast , I have a fever , aches, chills , slight headache and feel like my back is sunburnt. No kidney issues?
I have to have an MRI of brain with gadolinium. I had a CT with contrast once which was a bad hot feeling. Is gadolinium easier to handle? And if est GFR is 83 ml/min should test kidney first?
After tests mri brain, spine,w/wo contrast.eeg and neuro exam all with negative results.How confidently can i exclude ms.Been having severe anxiety over it.Was having tingling and numbness in leg. Mri showed stenosis, anteriorlisthesis and herniation?
MS: The results of the tests appear to show that the cause of your symptoms is due to physical changes as in stenosis and herniation and unlikely due to MS. You need to stop worrying and get on with your life ! ...Read more
Left arm weakness. EMG/nerve conduction study neg. Mri brain & c-spine (no contrast) neg. Phys Therapy no help. Whats the next step? What could it be?
Diagnosis: It sounds like there has been attempts, but it really does come down to the specific diagnosis for what is causing you this problem. Only then can things like prognosis and treatment options be known. Have you seen a neurologist? You might also request being referred to more of a tertiary care center if the diagnosis is not clear. ...Read more
Hi, what are the chances I have MS? I had a clean MRI of brain, with contrast. I have been having some tingly hands, floaters in eyes and dizziness.
Tests for MS: No single test helps diagnose of eliminate MS. A normal MRI however is a strong vote against MS as the cause. Floaters in the eyes and dizziness are not very strong signs of MS either. Tingling in the hands has many causes. For example, high blood sugar causes some of these symptoms. Carpal tunnel syndrome may cause symptoms in the hands. I doubt MS is the cause, but you should keep looking. ...Read moreSee 2 more doctor answers
I Wake up with tingling hands and feet sometimes one side or both sides. cold sensations in feet. When I get up and shake it off it goes away. Easily fatigued muscles but no clinical weakness.Had normal mri brain spine w/wo contrast . Could it be ms?
Uncertain - can be a myofascial pain syndrome.
Would see a neurologist and if you have then a rheumatologist ...Read more
No radiation is good: Mri scans can be done safely if there is no metal or metal fragments in the body. If there are (ie. Fragments in the eye from welding), this could be dangerous. The other issue is if contrast is given (usually for brain tumors). If a person has poor kidney function as determined by lab tests, the contrast can lead to the nephrotic syndrome which can severely damage the kidneys. ...Read more

Nonspecific: Foci indicates scattered lesions in different areas of the brain and need clinical correlation to diagnose significance. If the lesions are changing in size, number, location, and also are causing neurological symptoms, this likely is consistent with multiple sclerosis, but a variety of other possibilities could be considered. Discuss fully with your doctor. ...Read more
