Cardiology

The raw myocardial perfusion projection images are routinely evaluated for all of the following purposes EXCEPT:

The presence of a focal defect on rest images that was not seen on stress images, or the presence a focal defect on stress images that appears more severe on rest images is called:

What does Cardiomegaly mean?

A patient with possible acute myocardial infarction is injected with 99mTc pyrophosphate. The technologist needs to obtain images with better target-to background ratio. Which of the following time ranges gives the best results?

More than a few of the main imaging modalities use ionizing radiation for cardiovascular diagnosis and/or treatment. Which of the following modalities is used for coronary artery plaque and calcification imaging?

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:

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:

Atropine is an anticholinergic agent frequently used with dobutamine stress testing to increase:

The dose for cardiac first pass imaging studies must be contained in a volume not exceeding:

Through which of the following structure the deoxygenated blood passes through after leaving the right ventricle to reach the lungs?
