Brain MRI Test: Detects Many Diseases
A magnetic resonance imaging (MRI) machine scans the body and gives information about internal organs. Magnetic fields and radio waves are used that produce detailed images of the organs.
Usually, MRI scans are used to detect brain, bones, and muscles, such as soft tissue, chest, tumor-cancer, stroke, dementia or, migraine, blockage of arteries, and genetic disorders. This test is done for accurate information about the disease.
Brain MRI means a test of the brain. It is a method of diagnosis in which clear images of the brain are produced with the help of magnetic fields, radio waves, and computers. Brain problems can be detected with the help of brain MRI. It is one of the most sensitive imaging tests for the brain. It can provide detailed images of the parts of the brain that are not possible in CT scans and X-rays.
Why
is a brain MRI done?
Brain MRI is often used to detect conditions that
affect the brain.
· Birth defect
· Infection
· Hormonal disorders
· Tumor
· Stroke
· Bleeding
· Multiple sclerosis
· Fluid accumulation around the brain
· Brain damage from injury
· Inflammation of brain tissue
The physician may also suggest a brain MRI to determine
the cause of the following symptoms:
· Difficulty in speaking
· Vision problems
· Deafness
· Muscle weakness, numbness, or tingling
· Change in thinking or behavior
· Headache with other symptoms
· Weak memory, reduced ability to think
Procedure:
During this scan process, a magnetic field is created around the patient. The scanner then sends out radio waves, which change the alignment of the atoms in the body. When these atoms are re-aligned, they signal and the scanner converts these waves into images. Sometimes contrast dye is used in this process to enhance the quality of the images. It is a painless procedure. An MRI takes between 15 – 20 minutes.
