What are the common causes of abnormal MRI?
Abnormal Magnetic Resonance test (MRI) may be the result of numerous diseases and conditions. The abnormal MRI brain may be the result of stroke, blood clots and specific diseases such as multiple sclerosis and Alzheimer's disease. Various other conditions, such as Sciatica during MRI spine or blood clots, can also lead to abnormal MRI.
Magnetic fields and radio waves are used to make pictures during the MRI test. During the test patients lay on the table and are moved to the MRI machine. Patients may opt for an open MRI that provides some comfort to those who tend to become a claustrophobic or closed MRI. In some cases, for example during the brain MRI, the physician may require the patient to undergo a closed MRI machine to create clearer images. Contrast, dye that helps to improve images and helps to identify blood flow can be arranged at the discretion of the doctor for various reasons. When patients pThey say concerns about pain, inflammation or abnormal events, and can doctors can ask MRI to help eliminate or identify potential sources of discomfort and problems.

One of the most common reasons to order a doctorRI, is to help identify possible limb injuries. The knee MRI can lead to the identification of the torn meniscus, ligament or tendon. Arthritis in the joints of the arms and legs and bone fractures are some other possible reasons for abnormal MRI limbs.
