GBCAs allowed up to see the body light up during scans and has been a huge advance in medical scans. Unfortunately, no revolutionary technology goes without it's downsides Keep drinking water and pee it out.

  3. **Magnetic resonance imaging (MRI) is a method of scanning the body that provides clear, detailed pictures of organs and tissues 6. ** A contrast dye is sometimes injected into a vein during an MRI scan to improve the ability to see certain structures. All dyes used for MRIs contain a metal called gadolinium, which is attached to another.
  4. There are two major types of MRI scans, contrast and non-contrast. The primary difference is that for contrast MRIs, a dye (gadolinium-based) is given to the patient intravenously prior to the scan. Non-contrast MRI is great option for patients for whom dye is not recommended, pregnant women and kidney-compromised patients
  5. The MRI scanner has a short tunnel in the centre and a flat bed for you to lie on. While you are lying on the bed, it will slowly move into the centre of the tunnel where the pictures are taken. This movement is controlled by MRI staff. You may be given an injection of a special dye (contrast) into your veins
