Special Instructions: |
|
* Ensure phase enc. direction is A>P |
** Must be at least 2 concatenations/covers/acquisitions |
*** Cover from top of corpus callosum and include entire foramen magnum (to include PICA) |
**** A>P - Cover carotid and vertebral arteries; H>F - cover from origin of great vessels to skull base |
Indications: carotid artery dissection , neurological symptoms of infarction following trauma , vertebral artery dissection |
MRA Carotids/Neck – Three series; 1: Origin of Aortic Arch to include bilateral carotid, vertebral arteries. 2: Only include RCC from origin of Aortic Arch. 3: Only LCC from origin of Aortic Arch. Remove all irrelevant tissue and produce radial series with 18 images (one every 10 degrees); rotating around the vertical axis
