Updated 09/26/24 CT Sinuses Reviewed 05/14/25 Indications - acute/chronic sinusitis, rhinitis, runny nose, sinus/nasal mass, trauma, pre surgical evaluation. GENERAL SCAN NOTES Remove any metal from the imaging field of view (particularly earrings). Scan above any dental work to avoid artifact. Topogram - bottom of mandibles through top of skull. IV Contrast: 100 mL Omnipaque-300, inject at 2.5 mL/sec, 50 secs scan delay. Recon FOVs (send for all exams not just IGS): Routine Recons - above frontal sinuses to hard palate (top/bottom coverage), tip of nose to clivus (front/back coverage) and zygomatic arch to zygomatic arch (left/right coverage) Axial Thins - top of skull to horizontal portion of mandibles (top/bottom coverage), tip of nose to back of skull (front/back coverage) and external ear to external ear (left/right coverage) 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
