MRI is used to diagnose stroke, traumatic brain injury, brain and spinal cord tumors, inflammation, infection, vascular irregularities, brain damage associated with epilepsy, abnormally developed brain regions, and some neurodegenerative disorders.
1. Headache. Headaches are one of the most common neurological disorders—and there are a variety of different kinds of headaches, such as migraines, cluster headaches, and tension headaches.
Cardiovascular magnetic resonance imaging (CMR) allows the early diagnosis of various cardiovascular pathophysiologic phenomena in autoimmune diseases.
Abnormal results may be due to: Abnormal blood vessels in the brain ( arteriovenous malformations of the head ) Tumor of the nerve that connects the ear to the brain ( acoustic neuroma ) Bleeding in the brain.
Metallic fragments such as bullets, shotgun pellets, and metal shrapnel. Cerebral artery aneurysm clips. Magnetic dental implants. Tissue expander.
There are rare cases where someone can have MS but their MRI will look clear. This happens. That doesn't mean they can't get a diagnosis of multiple sclerosis, but it does make it significantly more difficult.
Drawbacks of MRI scans include their much higher cost, and patient discomfort with the procedure. The MRI scanner subjects the patient to such powerful electromagnets that the scan room must be shielded.
You'll typically be referred to a neurologist by a primary care provider who's already considered your symptoms and medical history, done a thorough exam, looked for underlying conditions, ordered laboratory tests or imaging and still feels treatment or diagnosis needs further investigation.
White matter lesions (WMLs) are areas of abnormal myelination in the brain. These lesions are best visualized as hyperintensities on T2 weighted and FLAIR (Fluid-attenuated inversion recovery) sequences of magnetic resonance imaging. They are considered a marker of small vessel disease.
Disorders of the nervous system
Infections, such as meningitis, encephalitis, polio, and epidural abscess. Structural disorders, such as brain or spinal cord injury, Bell's palsy, cervical spondylosis, carpal tunnel syndrome, brain or spinal cord tumors, peripheral neuropathy, and Guillain-Barré syndrome.
MRI is an imaging method that is very sensitive in detecting inflammation and also bone erosions. This makes MRI an interesting tool to measure the course of the disease in randomised clinical trials and this suggests that MRI may also be useful in the diagnostic process.
Positive symptoms were abnormal “superimposed” behaviours that included not only clonic jerking and abnormal movements but also hallucinations and paranoid delusions. Negative symptoms included loss of sensation, paralysis, and coma.
Among the most common are epilepsy, Alzheimer's, and stroke.
Neurological disorders are central and peripheral nervous system diseases, that is, they occur in the brain, spine, and multiple nerves that connect both.
The swift transmission of diagnostic information is important to both patients and referring physicians. The results from an MRI scan are typically interpreted within 24 hours, and the scans themselves are usually given immediately to the patient on a disc after the MRI is complete.
It usually takes 1 to 2 weeks for the results of an MRI scan to come through, unless they're needed urgently.
MRIs show common structural abnormalities among patients with depression and anxiety.
Brain scans alone cannot be used to diagnose a mental disorder, such as autism, anxiety, depression, schizophrenia, or bipolar disorder. In some cases, a brain scan might be used to rule out other medical illnesses, such as a tumor, that could cause symptoms similar to a mental disorder, such as depression.
Brain scans include several types of imaging techniques used to diagnose tumors, blood vessel malformations, stroke, injuries, abnormal brain development, and hemorrhage in the brain.
An MRI machine uses powerful magnets that can attract any metal in your body. If this happens, you could get hurt. It can also damage equipment that's implanted in your body -- a pacemaker or cochlear implant, for instance.
MRI is also contraindicated in the presence of internal metallic objects such as bullets or shrapnel, as well as surgical clips, pins, plates, screws, metal sutures, or wire mesh. If you are pregnant or suspect that you may be pregnant, you should notify your physician.
Keep your eyes closed or even wear a blindfold.
It's much easier in an open MRI it's wider than a standard scanner, so patients shouldn't feel any walls touching them.
