Either the test was done too soon and the damage hasn't shown itself within the brain or the damage such as those to the neurons is too small to be detected. The fact that you have had a negative MRI doesn't mean anything in terms of having a very serious brain injury.
Metallic fragments such as bullets, shotgun pellets, and metal shrapnel. Cerebral artery aneurysm clips. Magnetic dental implants. Tissue expander.
The Radiologist will send a report to the doctor who arranged the scan. They'll discuss the results with you. It usually takes 1 to 2 weeks for the results of an MRI scan to come through, unless they're needed urgently.
Conclusions There is a high rate of negative MRI and DWI among patients with minor stroke (a third) which has important management and research implications. A negative MRI or DWI does not exclude the diagnosis of stroke.
For the best diagnostic results, you need an MRI second opinion. Studies have found that not every radiologist will interpret the same MRI picture in exactly the same way. Your course of treatment depends on the exam results. Patients who want the best healthcare will get extra assurance with an MRI second opinion.
Safety. An MRI scan is a painless and safe procedure. You may find it uncomfortable if you have claustrophobia, but most people are able to manage it with support from the radiographer. Most modern MRI scanners have a wider tunnel, which can help reduce claustrophobia.
Body MRI scans are used to help diagnose or monitor treatment for a variety of conditions within the chest, abdomen, and pelvis. But recent research found that nearly 70% of all body MRI interpretations have at least one discrepancy.
For minor stroke, stroke of any age was found on 72% (90/125) of the 90-day MRIs and on 81% (101/125) of the baseline MRIs (P=0.05).
Usually, a silent stroke is discovered unexpectedly on a brain CT or brain MRI. These imaging tests can easily distinguish past strokes from recent strokes.
During a silent stroke, an interruption in blood flow destroys areas of cells in a part of the brain that is "silent," meaning that it doesn't control any vital functions. Although the damage will show up on an MRI or CT scan, it's too small to produce any obvious symptoms.
“They aren't doctors, and while they do know how to get around your anatomy, they aren't qualified to diagnose you.” That is true even though the tech likely knows the answer to your question. Imaging techs administer thousands of scans a year.
Results. The radiologist may discuss initial results of the MRI with you right after the test. Complete results are usually ready for your doctor in 1 to 2 days. An MRI can sometimes find a problem in a tissue or organ even when the size and shape of the tissue or organ looks normal.
Ideally, when your doctor orders an MRI, they should tell you how long it will take to obtain results. You will typically go to a follow-up appointment to review not only your results, but also the treatment options relevant to the MRI findings.
Either the test was done too soon and the damage hasn't shown itself within the brain or the damage such as those to the neurons is too small to be detected. The fact that you have had a negative MRI doesn't mean anything in terms of having a very serious brain injury.
MRI can be used to detect brain tumors, traumatic brain injury, developmental anomalies, multiple sclerosis, stroke, dementia, infection, and the causes of headache.
Possible findings. It is possible that an MRI may show that everything is completely normal; however, there are several things that could be seen on an MRI and this will vary depending on where in the body the scan is being done. An MRI is very good at showing up problems with soft tissues such as muscles and ligaments ...
What does that mean? A. A silent stroke refers to a stroke that doesn't cause any noticeable symptoms. Most strokes are caused by a clot that blocks a blood vessel in the brain. The blockage prevents blood and oxygen from reaching that area, causing nearby brain cells to die.
Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body. Sudden confusion, trouble speaking, or difficulty understanding speech. Sudden trouble seeing in one or both eyes. Sudden trouble walking, dizziness, loss of balance, or lack of coordination.
Tests will be done to rule out a stroke or other disorders that may cause the symptoms: You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests, but TIAs will not. You may have an angiogram, CT angiogram, or MR angiogram to see which blood vessel is blocked or bleeding.
One of the most common stroke mimics is a seizure, which researchers believe account for as many as 20% of all stroke mimics. Other common stroke mimics include migraines, syncope, sepsis, brain tumor and metabolic derangement (low sodium or low blood sugar).
In addition to the classic stroke symptoms associated with the FAST acronym, around 7-65% of people undergoing a stroke will experience some form of a headache. People describe a stroke-related headache as a very severe headache that comes on within seconds or minutes.
In about 70% of such misses, cancer was evident on prior CT or MRI and the physician overlooked it, while the other 30% were the result of misinterpretation.
Getting a second opinion on your imaging reports is common, and the process is fairly easy. Doctors can share your medical records with other providers in different facilities via secure systems. You can also talk to your doctor about recommendations for other specialists.
A false negative diagnosis made off an MRI scan could lead the neurologist and patient down an incorrect path and delay an accurate diagnosis, or potentially miss it entirely.
