Mid and distal, linear
47
What makes up the "seagull" image?
The AO with the splenic artery and common hepatic artery as wings
48
The CA is mostly easily seen in the ____ plane, slightly ____ to the pancreas.
Transverse, superior
49
The SMA is identified as a linear structure branching anteriorly from the AO inferior to the CA in the ____ plane.
Sagittal
50
Renal arteries are most easily seen in the ____ plane as small diameter curvilinear structures branching ____ from the AO.
Transverse, laterally
51
The LRA is difficult to identify in the ____ plane.
Sagittal

Why are the AO and its branches primarily evaluated?
To detect aneurysms and stenosis
