Fig. 3From: Value of virtual monochromatic spectral image of dual-layer spectral detector CT with noise reduction algorithm for image quality improvement in obese simulated body phantomAn axial virtual monochromatic image that show ROIs manually drawn on anterior abdominal wall, bilateral paraspinal muscle, liver parenchyma and a hypo-attenuating FLL. Other ROIs drawn in other axial image (not shown) to measure the attenuation of hyper-attenuating FLLsBack to article page
