1. First-line technique for evaluating myocardial
perfusion, viability and function is
a.Echo
b.Nuclear cardiac imaging
c.CMR
d.MDCT
e.X ray
2.All are true regarding nuclear cardiac imaging except
a. Resting perfusion abnormalities occur in areas supplied by a very severe (>85%) stenosis
b. stress is often used to increase sensitivity for rate-limiting stenoses
c. adenosine / dipyridamole/dobutamine are used in stress test.
d.current indications for pharmacological perfusion imaging include left bundle branch block and fixed rate pacemaker
e. SPECT may have better specificity than Rubidium-82 for detecting coronary artery disease

Rubidium-82 may have better specificity than SPECT for detecting coronary artery disease.
Many regard PET (using rubidium-82 to assess flow and FDG to assess glucose metabolism) as the best method for determining myocardial viability. Others believe that DE-MRI is equivalent or even superior to PET for assessing myocardial viability, and has superior spatial resolution.(Grainger)
