D. Flow may be turbulent across the valve and in the middle of the main pulmonary artery during diastole

Answer 5

A. Flow is systolic

B. Trivial regurgitation is common in the normal population

C. Flow should be laminar

Question 6

Select the preferred view for interrogating the atrial septum with colour Doppler:

A. Parasternal long axis

B. Apical 4 chamber

C. Subcostal 4 chamber

D. Parasternal short axis (level of the mitral valve)

Answer 6

C. Subcostal 4 chamber

Question 7

Select the statements that are correct regarding the normal colour Doppler imaging of the IVC:

A. Flow is continuous

B. Flow is typically blue from the subcostal long axis

C. Flow is biphasic

D. Flow is laminar

Answer 7

A. Flow is continuous

B. Flow is typically blue from the subcostal long axis

D. Flow is laminar

Question 8

The middle hepatic vein is a better indicator of flow reversal than the IVC because it is more parallel to flow.

A. True

B. False

Answer 8

A. True

Question 9

Blood flow on the right side of the heart may have a slightly darker hue in comparison to the left side due to being lower pressure resulting in slight lower velocities.

True

False
