Can an MRI............??!
Question: hi,
I am doing my science project on an MRI scan. I am almost done, but my last question is it always accurate? Like what types of conditions can an MRI miss? I can't find it anywhere.
Thank-you so much=)

I had an MRI miss a completely torn labrum in my shoulder. The doctor said that knees are fairly accurate but MRIs often miss tears in the shoulder.
if you have braces there will be black spots over your neck...i don't think that was what you were looking for but hope it helps
moving during an MRI can cause false readings
sometimes there can be flaws on the film as well
MRIs can only film tissue and bone... so it wouldnt be able to show blood.... but it CAN show a clot
An MRI scan can be used as an extremely accurate method of disease detection throughout the body. In the head, trauma to the brain can be seen as bleeding or swelling. Other abnormalities often found include brain aneurysms, stroke, tumors of the brain, as well as tumors or inflammation of the spine. Neurosurgeons use an MRI scan not only in defining brain anatomy but in evaluating the integrity of the spinal cord after trauma. It is also used when considering problems associated with the vertebrae or intervertebral discs of the spine. An MRI scan can evaluate the structure of the heart and aorta, where it can detect aneurysms or tears. It provides valuable information on glands and organs within the abdomen, and accurate information about the structure of the joints, soft tissues, and bones of the body. Often, surgery can be deferred or more accurately directed after knowing the results of an MRI scan.
They can't effectively scan metal. A plate in your knee would keep an MRI from doing an effective scan.
What you see on an MRI depends on how it is tuned. The standard diagnostic MRI sees WATER primarily. It does not see bone well. So, for example, if a bony spur is pinching a nerve root, MRI may miss it where a standard myelogram would show it. If tuned for iron, it shows the iron in hemoglobin, and thereby gives a picture of the blood vessel the hemoglobin is in. Here is a link to give you more information:http://dir.nhlbi.nih.gov/lab...
