Updated 05/03/24 CT Maxillofacial/Orbits Reviewed 05/14/25 Indications - trauma, foreign body, cellulitis, infection, abscess, proptosis, diplopia, mass. GENERAL SCAN NOTES Remove any metal from the imaging field of view (particularly earrings and dentures). Topogram: Maxillofacial - top of frontal sinuses through the bottom of mandible. Orbits - Top of frontal sinuses through the bottom of maxilla. Craniocaudal scan coverage: Maxillofacial - top of frontal sinuses through the bottom of mandible. Orbits - Top of frontal sinuses through the bottom of maxilla. Adjust FOV (field of view) on topogram to smallest without cropping anatomy. IV Contrast: 100 mL Omnipaque-300, inject at 2.5 mL/sec, 45 secs scan delay. 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
