Instructions And Patient Preparation<\/h3>\n
\n
Instructions<\/dt>\n
• The Neck TOF sequences are typically done only if the contrasted neck sequences are limited
• If perfusion-weighted imaging (PWI) or MRA Coronal is performed, a Power Injector should be used to administer contrast agent (split dose 1\/3 MRA, 2\/3 PWI)
• Contrast sequences provide superior resolution and image quality for MRA in the neck<\/dd>\n
Position<\/dt>\n
Supine, head first<\/dd>\n
Coil<\/dt>\n
Head. If Neck is being imaged use NVPA or HNU<\/dd>\n
