Figures
- FIGURE 1.
Box plot comparing median and distribution of SDS for FBP and WBR. Data indicated no difference between 2 distributions (F = 0.91; P = 0.3421). Whiskers represent 1.5 times the interquartile range. ○ = mild outlier; • = severe outlier.
- FIGURE 2.
Box plot comparing median and distribution of left ventricular EF (percentage) for FBP and WBR. Data indicated significant difference between 2 distributions (F = 6.13; P = 0.0157).
- FIGURE 3.
Linear regression plot indicating relationship between FBP EF and WBR EF. Equation describing plot was as follows: FBP EF = 2.1243 + (1.0666 × WBR EF).
- FIGURE 4.
Myocardial images in short-axis (left), vertical long-axis (middle), and horizontal long-axis (right) orientations showing normal radiopharmaceutical distribution with WBR techniques (A), normal radiopharmaceutical distribution with FBP techniques (B), abnormal radiopharmaceutical distribution with WBR techniques (C), and abnormal radiopharmaceutical distribution with FBP techniques (D).
