Case 10

Presentation:

Assess patient for coronary artery disease

Question 1:

What are some heart-related artifacts in myocardial perfusion imaging (MPI)?

Question 2:

Cardiac perfusion imaging is also known as nuclear stress testing. Stress may be exercise-induced or pharmacologically induced.

i. What are some medications that may interfere with exercise stress testing?

ii. What are some medications that may interfere with pharmacologic stress testing?

Question 3:

What are some heart-related artifacts in myocardial perfusion imaging (MPI)?

a. Left anterior descending artery (LAD) – Defects in the lateral wall, posterior wall, posterior inferior wall and apex

b. Left circumflex artery (LCx) – Defects in inferior wall, posterior inferior wall, right ventricular wall

c. Right coronary artery (RCA) – Defects in septum, anterior w

d. Left main coronary artery (LCA) – Defects in anterior wall, septum and posterolateral wall
