Objectives For Week Six - Cardiology

1. Identify the different radiopharmaceuticals and know the pathophysiology of the ^99mTc agents
2. Differentiate ischemia and infarct on a nuclear cardiology stress test
3. Define the process of stressing a patient: pharmacological and treadmill
4. Know the different types of tomographic slices of the heart and where the base and apex is located
5. Identify and briefly review the concept of a polar maps/bull's eye.
6. Determine how a MUGA and a gated MPI are acquired.
7. Calculate %EF of the LV. (ED = 77,656 cts and ES = 44,562 cts) (42.6%)
8. Define the types of wall motion seen on a gated cardiac.
9. What is the ingredient that allow us to label RBCs with ^99mTc.

Terms to think about

1. %EF, ED(N), and ES(N)
2. Hypokinesis, akinesis, and dyskinesis
3. Short axis, vertical long and horizontal long
4. Myoview/tetrofosmin and Sestamibi/Cardiolite
5. Vertical Long, Horizontal Long, and Short Axis
6. Gating the myocardium
7. R to R interval
8. Ischemia vs. infarct
9. Bull's eye or polar maps

Questions

1. From #8 calculate the %EF.
2. What is the difference between Myoview and Cardiolite?
3. How do you gate the myocardium?
4. When imaging stress/rest what does normal, ischemic, and infarct look like?
5. Define hypo/a/dyskinesis.
