- FIGURE 1.
Linear regression plot demonstrates strong correlation between 99mTc-TET gated SPECT ejection fraction using single-acquisition protocol (TETRO[S] GSPECT EF) and 18F-FDG gated SPECT ejection fraction using single-acquisition protocol (FDG[S] GSPECT EF).
- FIGURE 2.
Linear regression plot demonstrates strong correlation between 99mTc-TET gated SPECT ejection fraction using dual-acquisition protocol (TETRO[D] GSPECT EF) and 18F-FDG gated SPECT ejection fraction using dual-acquisition protocol (FDG[D] GSPECT EF).
- FIGURE 3.
Vertical long-axis slices from 99mTc-TET (first row) and 18F-FDG (second row) studies of same patient using dual-acquisition protocol (A) and single-acquisition protocol (B). Inferior wall perfusion defect (arrow) but viable myocardium is seen on dual-acquisition 18F-FDG study, but perfusion abnormalities (arrow) are underestimated on single-acquisition 99mTc-TET study, likely related to downscatter from 18F 511-keV photons.
