Mri (Definition)

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

My mother's brain MRI shows hyperintense focus in t2w1/flair images in cerebellar vermis. Impression: ischemic focus in the cerebellar vermis. Explain.

My mother's brain MRI shows hyperintense focus in t2w1/flair images in cerebellar vermis. Impression: ischemic focus in the cerebellar vermis. Explain.

Look at entire study: T2 and flair signal can be evidence of an "ischemic focus, " otherwise a stroke. However, other things could be in the mix, such as a tumor or demyelinating process. The radiologist will have looked at the other sequences. Sometimes, however, it can be tough to tell. ...Read more

What is a t2 fluid signal in a brain mri?

What is a t2 fluid signal in a brain mri?

T2: Technique shows fluid or fluid containing tissues to be bright (or white) on mri. For example, the ventricles will be bright white on t2 as they contain cerebrospinal fluid. ...Read more

Brain Mri states; minimal signal within a left ethmoid air cell, what does that mean?

Brain Mri states; minimal signal within a left ethmoid air cell, what does that mean?

Probably nothing: The radiologist probably is referring to minimal sinus fluid, but to be sure you should ask him/her directly ...Read more

What does parietal periventricular signal alteration on a brain MRI mean?

What does parietal periventricular signal alteration on a brain MRI mean?

A change: There is a change in the signal in the tissue that surrounds the brain ventricles. That is not very specific. For example as we get older than say 20? then this finding may become more prominent. It also depends on why you had the study done in the first place. It may reflect why you are having symptoms. To put it all together talk to your doctor. ...Read more

My brain MRI says one small area of increased signal on flair images in the right parietal white matter- what does this mean?

My brain MRI says one small area of increased signal on flair images in the right parietal white matter- what does this mean?

May be nothing or?: Your clinical history- the reason you had the MRI- may be a clue.

Many brains show one small area of flair signal. These are often due to headaches, head injuries, high blood pressure, changes in blood flow, etc. They are not by themselves an indicator of much.

If you had many of these, and symptoms of MS, they could be related. A single small area though is not alarming. ...Read more

I did brain MRI some of the results are: there's signal void from the interior and posterior circulation. What does it means?

I did brain MRI some of the results are: there's signal void from the interior and posterior circulation. What does it means?

Need more info: This is likely a statement from the findings section of the mri. Please check the final impression of the report and review the results of your scan with your doctor who ordered the scan. Unfortunately, it is difficult to provide you with more information without seeing the images and reviewing the report. ...Read more

Brain MRI result:there is signal void from the anterior and posterior circulation. Is this good or bad? Should I worry and seek for help?

Brain MRI result:there is signal void from the anterior and posterior circulation. Is this good or bad? Should I worry and seek for help?

More context needed: The best answer to your question will come from the person who ordered the test. The words used are radiology "shop talk" and often don't mean much in and of themselves. Most of the time, no worries...Sometimes, yes. Since you're so young ; since you've had not just an MRI but mra too then, again, your physician must've had reason to order these tests. They will have the answers you seek. ...Read more

Brain MRI result: there is no signal void from the anterior and posterior circulation what's the medical definition of it and is it bad or not?

Brain MRI result: there is no signal void from the anterior and posterior circulation what's the medical definition of it and is it bad or not?

Signal Void Brain: On mri, in certain sequences there should be a lack of signal (ie. A black appearance) within the blood vessels. This normal appearance suggests that blood is flowing normally within these blood vessels. If there is a lack of signal void, this could suggest either abnormal blood flow or a complete lack of blood flow. This is abnormal and is concerning. Oftentimes this is associated with a stroke. ...Read more

Brain MRI showed low marrow signal is this concerning? I was having a followup MRI for an incidental meningioma found Dec 2016. It was stable.

Brain MRI showed low marrow signal is this concerning? I was having a followup MRI for an incidental meningioma found Dec 2016. It was stable.

It is insignificant: Marrow signal reported in a MRI is rarely helpful. Its significance, if any, is minimal. I would not be concerned about it. Just focus on the Meningioma. ...Read more

What does T2 Flair minimal periventricular hypertensive signal in brain MRI means?

What does T2 Flair minimal periventricular hypertensive signal in brain MRI means?

Usually nothing: There are many reasons for FLAIR periventricular hyperintensity. Usually, especially in older people, it means changes in the blood vessels in the brain. This is often due to a combination of atherosclerosis, demyelination (loss of the "white matter" covering the nerves), and scarring. It is very common and usually clinically insignificant. This is likely your case by use of the word "minimal." ...Read more

What does nonspecific heterogeneous marrow signal suggestive of red marrow reconversion on brain MRI means?

Red marrow: Reconversion usually indicates a chronic hypoxic or anemic state. For example, it is sometimes seen in heavy smokers. Talk to your doctor about what it means in your case. ...Read more

Doc ordered brain MRI for lhermitte's signal. Wouldn't a spine MRI also be necessary to rule out ms?

Doc ordered brain MRI for lhermitte's signal. Wouldn't a spine MRI also be necessary to rule out ms?

Agree with you: I do appreciate the thinking that resulted in brain mri, but lhermitte's can be due to non-ms mechanisms such as b-12 deficiency, and would certainly add a cervical mri. However, in defense of your doc, the decision could have been influenced by insurance restrictions. (choices mandated by non-physicians, who have gained control over the marketplace). Talk with your doc, as I think he means best. ...Read more

If a brain MRI shows no acute process but only a nonspecific signal change in left parietal, is it advisable to do a CT scan considering its risk?

If a brain MRI shows no acute process but only a nonspecific signal change in left parietal, is it advisable to do a CT scan considering its risk?

Not necessary: It is not necessary to undergo a CT. Of course it would depend on why you had the MRI in the first place. Most of these findings that are called nonspecific are vascular spaces and not by themselves a cause to worry ...Read more

How can a brain MRI be done?

MRI: You will be asked to rest on your back and not move your head during the mri. You will be moved into the scanner. The MRI machine has enormously powerful magnets which will orient hydrogen molecules into a single direction. When a when the magnet energy is changed, the hydrogen atoms give off energy which will be picked up by the computer. ...Read more
