Updated 04/27/24 CTA Arms Reviewed 05/14/25 Indications - peripheral artery disease, claudication, ischemia, absent pulses, aneurysm, trauma. Bill under CT Angiography UE charges. GENERAL SCAN NOTES Remove any metal from the imaging field of view. Symptomatic arm (or both) over head with head tilted away from symptomatic arm. Topogram - mid chest to cover arch through fingers (obtained during end inspiration). Craniocaudal scan coverage - mid chest to cover arch through fingers (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 aortic arch triggered at 100 HU. A peripheral IV must be on the side opposite from the more symptomatic arm. A central line used for injection can be in either arm. 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
