The diagnostic phase associated with a CT scan?


Before a visit to CT scan centre in Mumbai, you need to be aware more about the procedure in details. The basic purpose of a CT scan is that it goes on to rely on the use of X rays that works out to be a special type of radiation which goes on to take pictures of what happens inside your body. In a lot of ways it is similar to a plain X ray but it takes pictures of cross sections of your body instead of a single one. The chances are that you may be asked to drink a special liquid or a dye may be given during the course of the injection. In the scanner there is a round opening in the centre, with a flatbed where you can lay down. The moment you are lying down it will slowly open into the opening where the pictures are expected to be taken. This movement is being administered by the CT staff.
