Updated 03/09/25 CTA Liver Pre-SIRT Reviewed 05/14/25 Indications - pre procedure planning for radioembolization of liver mass. Use CT Angio Combo AP w/ + w/o Contrast charge. Do not use CT 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 - Lung bases through pubic symphysis on both phases (obtained during end inspiration). Adjust FOV (field of view) on topogram to smallest without cropping anatomy. IV Contrast: Administer weight-based Omnipaque-350 - 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 100 HU. Oral Contrast: generally 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.
