You will be asked to change into a hospital gown in a changing room. You will be taken from the changing room into the computer tomography (CT) scanning room. You will be asked to lie on the CT scanning table on a thin plastic mattress. Plastic tape with small metal markers attached to it will be taped onto your back. The scanning table will be moved into the scanner and CT images or pictures of your spine will be taken. The tape with the markers is used to mark the spot, or level, in your spine where the needle for the lumbar nerve root sleeve injection will enter the skin. The spot will be marked on your skin with a pen and the tape removed.
