    FIGURE 1. 

    Two-day 99mTc-tetrofosmin SPECT images (top 2 rows, stress and rest short-axis slices; middle 2 rows, stress and rest horizontal slices; bottom 2 rows, stress and rest vertical slices) show absence of activity in apical wall and decreased activity in apical anterior wall. Increased activity in inferior to the inferior wall is noted on short-axis slices (arrowheads); large areas of activity (arrows) are noted in basal region on vertical and horizontal images.

    (A) Raw-data images in anterior projections at stress (right) and rest (left) on 2-d 99mTc-tetrofosmin SPECT study show duodenogastric reflux (arrowheads). (B) Raw-data images in left lateral projections on 2-d 99mTc-tetrofosmin SPECT study show extracardiac activity (arrows) in posterior aspect of heart (H) at rest (left) and stress (right).
