Figure 1b. Single short-axis-view true FISP MR images (3.2/1.2) obtained in patient with impaired LV systolic function. (a) ED (left) and ES (right) images show inclusion of trabeculae in LV cavity volume. (b) ED (left) and ES (right) images show exclusion of trabeculae from LV cavity volume. The effect of trabeculae on the drawing of endocardial border contours is evident.
