1 Fig. 5. Contrast-enhanced axial chest virtual monoenergetic dual-energy CT imaging. A. Three round regions of interest are placed in left atrium, back muscle, and subcutaneous fat in anterior chest wall, respectively, on axial chest CT image. B. Graph illustrating changes in CT value in three regions of interest as function of energy. Iodine in blood (white line) shows higher CT values at lower keV, while fat (orange line) reveals lower CT values at lower keV. In contrast, muscle (yellow line) demonstrates almost constant CT values in range of 40–190 keV. Fig. 5. Contrast-enhanced axial chest virtual monoenergetic dual-energy CT imaging. A.
