Article Figures & Data
Figures
- FIGURE 1.
Schematic representation of processing steps of factor analysis to yield input function and regional myocardial TACs. LV = left ventricle; RV = right ventricle.
- FIGURE 2.
Right ventricular (RV) (A), left ventricular (LV) (B), and myocardial (C) factor images obtained from first step of factor analysis. All dynamic H215O PET studies gave consistent results.
- FIGURE 3.
Input functions by factor analysis and arterial sampling. Blood samples were drawn from radial arteries.
- FIGURE 4.
Representative TACs of left ventricle and myocardium. Curves were obtained by factor analysis (A) and ROI method (B).
- FIGURE 5.
Correlations between rMBF by factor analysis and rMBF by microsphere studies (r = 0.95; y = 0.95x + 0.26) (A) and between rMBF by ROI method and rMBF by microsphere studies (r = 0.93; y = 0.88x − 0.01) (B).
