What does Cardiomegaly mean?
2.
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?
3.
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:
4.
Which of the following medications can be used as an adjunct to myocardial perfusion imaging (MPI) pharmacological stress testing?
5.
What heart chamber does the aorta arise from?
6.
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:
7.
The anatomical structure dividing the heart into two functionally separate and anatomically distinct units and separates left atrium and ventricle from the right atrium and ventricle is called:
8.
The dose for cardiac first pass imaging studies must be contained in a volume not exceeding:
9.
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:
10.
The raw myocardial perfusion projection images are routinely evaluated for all of the following purposes EXCEPT:
