- FIGURE 1.
Dipyridamole 99mTc-tetrofosmin–rest 201Tl-chloride myocardial SPECT images show large area of intense radioactivity below and adjacent to inferior wall of LV in 5 to 6 o’clock region, as indicated by arrowheads on short-axis images (top row); activity in inferior wall, shown on vertical long-axis images, appears to be more prominent than that of rest (201Tl-chloride SPECT, lower panel); these findings mimic reverse redistribution of inferior wall of LV. Right ventricle is visualized at stress and on rest.
- FIGURE 2.
Polar map displaying results of perfusion from gated 99mTc-tetrofosmin myocardial SPECT shows intense radioactivity in inferior portion, in 5 to 6 o’clock region (arrowhead, perfusion display). On wall motion display, there is an area of absent radioactivity (arrowheads). Absent regional ejection fraction (EF) in the regional EF display is indicated by arrows.
- FIGURE 3.
Raw data images obtained from left anterior oblique (left) and anterior (right) views show areas of abnormal radiotracer accumulation in subdiapharmatic region, including large amount of radioactivity in gastric region (1), below and overlapping inferior wall of LV (H). Gallbladder (gb) and liver are also identified.
