A small apical defect refers to a condition where the tip of the heart does not get blood during the stress procedure and the affected area due to lack of blood flow is so small, that it reverses back to its original form. 34 , 5 , 6 As with conventional SPECT technology, this new technology poses specific imaging challenges that will be discussed in this chapter. Stress test reads there is a mildly reduced perfusion defect of moderate size in the inferior wall and the defect in the inferior segment is reversible.
Myocardial stress is achieved either by exercise (preferred) or pharmacologically with regadenoson, adenosine, or dipyridamole (as an alternate to exercise) using standard protocols.
