Question

While scanning in the apical 2 chamber view, you are trying to assess flow in a possible aneurysm in the thoracic aorta. Which of the following adjustments will assist in improving color flow in the aorta?

A) Increase the wall filter setting
B) Activate the zoom function over the aorta
C) Increase the color sample size
D) Change the velocity color map to a variance map

Answer 1

To assess flow in a thoracic aorta aneurysm using apical 2 chamber view, activating the zoom function over the aorta and increasing the color sample size are beneficial adjustments. Changing to a variance color map can also distinguish flow types.

Step-by-step explanation:

When trying to assess flow in a possible aneurysm in the thoracic aorta using an apical 2 chamber view, the best adjustment to improve color flow would be to activate the zoom function over the aorta. This will allow for a more focused and detailed observation of the blood flow patterns within the aorta. Increasing the sample size of the color Doppler can also help in visualizing the flow in larger vessels, while changing to a variance color map may aid in distinguishing turbulent flow from laminar flow, which could be useful in specific situations. However, increasing the wall filter setting would likely remove useful information about low-velocity flows and should be adjusted carefully.
