Updated 03/09/25 CT Pancreas Reviewed 05/14/25 Indications - pancreatic mass, pancreatic duct dilatation, biliary dilatation, chronic pancreatitis, status post Whipple or distal pancreatectomy. Use CT AP w/ + w/o Contrast charge. Do not use CT Angio Combo AP w/ + w/o Contrast charge. GENERAL SCAN NOTES Move the patient's arms over his/her head if possible. Remove any metal from the imaging field of view. Topogram - Lung bases through pubic symphysis (obtained during end inspiration). Craniocaudal scan coverage: Pre contrast - abdomen only (lung bases to iliac crests) (obtained during end inspiration). Arterial phase - abdomen only (lung bases to iliac crests) (obtained during end inspiration). Venous phase - abdomen/pelvis (lung bases through pubic symphysis) (obtained during end inspiration). Delay phase - abdomen only (lung bases to iliac crests) (obtained during end inspiration). If only the abdomen is ordered, only image the abdomen regardless of what coverage areas below indicate. Adjust FOV (field of view) on topogram to smallest without cropping anatomy. IV Contrast: Administer weight-based Omnipaque-300 - 1 mL/kg up to 150 mL (100 mL minimum). Inject at 4 mL/sec followed by 40 mL saline flush, 20-gauge or larger in forearm or more proximal. Bolus track off proximal abdominal aorta triggered at 150 HU + 15 secs. Oral Contrast: Patient receives 16 oz water 20 mins prior to exam and 8-16 oz more just before getting on the scanner. If patient has undergone prior pancreas surgery, use regular water-soluble contrast instead with same timing. 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.
