Figure 1 (A) Tomographic cross-sectional image of the heart at the level of the mid-LV, showing a traced anterior wall region-of-interest, and contrast media in the LV cavity. (B) Time-density curves consequent to transit of contrast media through the anterior cardiac wall region of interest (closed circles), depicting the modeling of intra- and extra-vascular curves (triangle and square symbols, respectively). LV = left ventricle.
