Updated 03/24/25 CT Esophagram Reviewed 05/14/25 Indications - concern for esophageal perforation or fistula. Use CT Chest w/o Contrast if IV contrast is not given and CT Chest w/ Contrast if IV contrast is given. GENERAL SCAN NOTES Move the patient's arms over his/her head if possible. Remove any metal from the imaging field of view. Have the patient cough a few times to clear secretions. This reduces incidence of small lung nodules. Topogram - lung apices through diaphragm (obtained during end inspiration). Craniocaudal scan coverage - lung apices through adrenal glands (obtained during end inspiration). Adjust FOV (field of view) on topogram to smallest without cropping anatomy. Scan parameters and recons are the same as routine chest protocol. IV Contrast: 100 mL Omnipaque-300, inject at 2 mL/sec, 30 secs scan delay. Oral Contrast: Have the patient drink 8-16 ounces of Omnipaque oral contrast immediately before getting on the scanner. Stop the patient from drinking more contrast if he/she begins to cough or choke. Do not use Gastrografin, Gastroview or barium contrast even if the order comments say to use one of them. 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
