Focal cystic high-attenuation lesions: Characterization in renal phantom by using photon-counting spectral CT - Improved differentiation of lesion composition

Our study results showed that spectral CT has the potential to help effectively characterize hyperattenuating lesions in a renal phantom by identifying proteinaceous/hemorrhagic lesions by assessing their distinct levels of attenuation, as well as by detecting iodine-containing lesions by analyzing their specific k-edge discontinuities.
