ECHO 1 Final Questions
and Answers


Which view do you start with in cardiac imaging?


Ans- 2D




Which imaging modes are used?


Ans- 2D, m-mode, color Doppler, Doppler




What does Doppler allow us to analyze?


Ans- flow




What does color Doppler allow us to analyze?


Ans- visually analyze flow

,Which view is M-mode used in?


Ans- parasternal




When can M-mode be used in other views?


Ans- if it's a technically limited study




What does M-mode do?


Ans- looks at motion and allows for measurement of structures and calculations

of cardiac function




Why is color Doppler used in each view?


Ans- show blood flow




What does it mean if blood flows backwards through a valve?


Ans- it is leaky/there is backflow




What does red color Doppler mean?

,Ans- blood flow towards the transducer




What does blue color Doppler mean?


Ans- blood flow away from the transducer




In systole, which valves are opened?


Ans- aortic and pulmonic




In diastole, which valves are opened?


Ans- mitral and tricuspid




What happens in systole?


Ans- ventricles contract




What happens in diastole?


Ans- ventricles fill

, What is mosaic?


Ans- the valve is closed, but blood is flowing backwards still




What is Doppler used for?


Ans- analyzing blood flow




Which view is Doppler used in?


Ans- view where abnormality is seen; could be multiple




What are the things Doppler assesses?


Ans- 1. demonstration of blood flow/direction of flow


2. normal velocity/spectrum for each valve structure


3. assess severity of abnormal flows (degree of stenosis, leak, shunt flow)




What are the four views in cardiac imaging?


Ans- PLAX, PSAX, apical, subcostal
