34

IMA originates from the _____ aspect of the AO, and courses _____ and _____ to the _____, _____, and _____ which it supplies.

35

The median sacral artery supplies the _____ and the most _____ branch of the AO.

36

AO should not exceed _____ in size at any point.

3cm

37

The AO courses _____, and _____ in size and lies more _____ to the abdomen.

Inferiorly, decreases, shallow

38

The best way to decrease observer variation when measuring the AO is to take the AP measurement in the _____ plane.

Sagittal

39

The 3 layers of the aorta are

Tunica intima, tunica media, tunica adventitia

40

Arteries have a thicker _____ to allow for greater elasticity.

Tunica media

41

What is the primary function of the AO?

Channel blood to organs and tissues to ensure oxygenation and metabolism.

42

43

Arterial vasculature should display a(n) _____ center with _____ walls that clearly delineate from adjacent structures.

Anechoic, echogenic

44

T or F? Larger vessels will display significant pulsatility.

True

45

The AO is a tubular, highly pulsatile structure that is ____ and slightly to the ____ of the spine.

Anterior, left

46

The AO courses more anteriorly at the _____ regions, until it bifurcates and courses _____.

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

52

T or F? The IMA is consistently demonstrated with ultrasound.

False

53

Renal arteries are most easily seen in the ____ plane. However, the RRA might be identified in the ____ plane as it is directly ____ to the IVC.

Transverse, sagittal, posterior

54

The AO bifurcation is most easily identified in the ____ plane.

Transverse

55

Why are the AO and its branches primarily evaluated?

To detect aneurysms and stenosis

56

T or F? Doppler can aid in identifying stenosis because it indicates flow patterns within the vasculature.

True

57

What is the echogenic material seen surrounding the SMA in a transverse scan plane that helps to identify it?

Parapancreatic fat
