Quantitative Lesion Characterization
at 50cm FoV
Spectral Imaging’s potential to enhance lesion charac-
terization is seen here with the two lesions displayed
on the images. Utilizing GSI and viewing the images at
lower spectral energy, the lesion is more conspicuous,
and the differentiation of the non-enhancing cyst
and enhancing lesion is well depicted on the spectral
curves, normalized to the liver parenchyma.
