The venous blood returning via the superior vena cava (SVC) and inferior vena cava (IVC) enters the heart at the:
2.
What heart chamber does the aorta arise from?
3.
The sympathetic nervous system has great influence on cardiovascular physiology and is responsible for regulating myocardial blood flow, heart rate, and the contractile performance of the heart. Which of the following radiotracers can be used for imaging the sympathetic nervous system of the heart?
4.
If the time between two successive R points is 1 second, a beat length acceptance window of 100% allows accumulation of data from cardiac beats:
5.
A defect that is present on stress images, and not seen or present to the lesser degree on resting images is called:
6.
A two-dimensional illustration of a three-dimensional allocation of the radiotracer in the myocardium which allows visualization of perfusion defects in a compressed format is known as:
7.
Which of the following arteries supplies the myocardium?
8.
What is the way that the blood return to the heart from small intestine?
9.
Attenuation artifacts of tomographic myocardial perfusion imaging may decrease the diagnostic accuracy of the technique, predominantly due to:
10.
Myocardial ischemia could be distinguished from myocardial infarction by analysis of PET images of the perfusion tracer N-13-labeled ammonia and the glucose analogue FDG. Region with “flow-metabolism mismatch” – decreased flow with normal increased FDG activity – represents:
