FIGURE 2.
Effect of respiratory-motion compensation. The images without and with respiratory compensation are shown at 2 DCE phases: 1 pre-contrast phase and 1 equilibrium phase (td = 4 minutes). The contrast agent (CA) concentration curve of the pancreas is displayed. Images with compensation show less artifacts and improved structure delineation. The red thick arrows mark the pancreas, which is much sharper with less artifacts on images with compensation. The yellow thin arrows mark small vessels, which show clearer boundary and improved contrast on images with compensation. The green dashed arrows point out that the CA concentration curve with compensation is much cleaner with far less oscillation
