- FIGURE 1.
Illustration of deformation of the analytic model of time–activity curve M(t) with polynomial function Q(t) to fit acquired noisy data (red dots) and produce 3-dimensional parametric image of local TES.
- FIGURE 2.
Local EF (top 2 rows) and local TES (bottom 2 rows) assessed for control subject. First 2 columns concern RV, and last 2 columns concern left ventricle. LEF and REF = mean ± SD of left and right ventricular EF, respectively; L-SD-TES and R-SD-TES = σ-TES measured for left ventricle and RV, respectively.
- FIGURE 3.
Local EF (top 2 rows) and local TES (bottom 2 rows) assessed for patient with localized ARVD. First 2 columns concern RV, and last 2 columns concern left ventricle. LEF and REF = mean ± SD of left and right ventricular EF, respectively; L-SD-TES and R-SD-TES = σ-TES measured for left ventricle and RV, respectively.
- FIGURE 4.
Local EF (top 2 rows) and local TES (bottom 2 rows) assessed for patient with diffuse ARVD. First 2 columns concern RV, and last 2 columns concern left ventricle. LEF and REF = mean ± SD of left and right ventricular EF, respectively; L-SD-TES and R-SD-TES = σ-TES measured for left ventricle and RV, respectively.
