Welcome

As a general rule, scan field should be from Carina to Sella turcica when patient is positioned properly. Be aware of diagnosis to ensure that all relevant anatomy is included. If patient is unable to position properly and a large portion of brain/skull will need to be scanned please clear with radiologist to ensure that no additional orders will need to be obtained
