Instructions And Patient Preparation<\/h3>\n
\n
Instructions<\/dt>\n
• This exam is tailored to the patient’s condition and is meant for rapid assessment at lower resolution
• If perfusion-weighted MRI (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
