An MRI Scan – an acronym for Advance Diagnostic Center , a Test process where powerful and controlled magnetic fields, radio waves and computer technology combine to produce highly detailed pictures of the inside of the human body. Since an MRI Scan is usually done on the brain, the procedure or Test is sometimes also simply called a Brain MRI or Cranial MRI. An MRI Scan differs from a CT Scan or X-Ray in that it doesn’t involve the ionizing radiation of X-rays, which is known to sometimes leave behind harmful effects over the long term. The biggest advantage that an MRI Scan has (over, say, the CT Scan or Tomography Scan) is that it produces 3D images instead of 2D images through 3D reconstruction is available now for CT scan also. The extra ‘vision’ and ‘understanding’ this additional dimension of depth offers is invaluable for medical purposes – be it diagnosis or treatment. This makes an MRI Scan highly effective (and unmatched) when it comes to analyzing small structures of the brain, such as, for example, brain stem or the pituitary gland. An MRI Scan usually doesn’t have any risks associated with it.
