MRI is an abbreviation used for ‘magnetic resonance imaging’. It’s a technique that uses a magnetic field and radio waves in order to create detailed images of the organs and tissues within the body. Majority of MRI machines are large, tube-shaped magnets. When a person lies inside an MRI machine, the magnetic field temporary realigns hydrogen atoms in her/his body. Radio waves make these atoms to produce faint signals, which are used to create cross-sectional images- more like slices in a loaf of bread.
The MRI machines can also produce 3-D images that may be viewed from different angles. We at Vimhans PrimaMed Institute of Radio Diagnostics & Imaging are equipped with latest technology equipment and perform thousands of MRIs each year.
Why it is done?
MRI is a noninvasive procedure for the doctors to examine human organs, tissues and skeletal system. It generated high quality images of the inside of the body helping diagnose a number of problems.
Brain and Spinal Cord
MRI is frequently performed to help diagnose:
• Aneurysms of cerebral vessels
• Multiple sclerosis
• Spinal cord injuries
• Disorders of the eye and inner ear
• Brain injury from trauma
