Updated 09/28/25 CT Lumbar Spine Pre Surgical Reviewed 09/28/25 Indications - pre surgical evaluation prior to lumbar spine surgery. Use this protoocol for any pre surgical indication and if the order mentions Mazor or Karma protocols. Use CT Spine Lumbar without Contrast charge. GENERAL SCAN NOTES Move patient's arms over head if possible. Remove any metal from the imaging field of view. Topogram - T12 through bottom of SI joints. Craniocaudal scan coverage - T12 through bottom of SI joints. FOV should be between 200-250 mm. Matrix must be 512 x 512. IV Contrast: not given for this protocol. For GE scanners, it is essential for the 1st recon thickness on the scanner to match the 1st recon thickness in this protocol book for the prescribed Noise Index to be valid. The 1st recon should generally be the thickest recon in the protocol. SIEMENS PARAMETERS & RECONS Scan
