In PET/CT studies, artifacts can occur in CT/AC scans when parameters are adjusted to reduce CT radiation exposure to very low levels, and these can in turn cause PET errors. Scanning at 80 kVp instead of 120 or 130 kVp can result in attenuation correction errors due to photon starvation, especially in large patients, and to beam hardening in the skull. We addressed this problem by segmenting CT images...
Three stilbene oligomers, davidiols A–C were isolated from the roots of Sophora davidii in addition to the seven known phenols, leachianone A, sophoraflavanones G, H and I, miyabenol C, α-viniferin and ε-viniferin. Their structures and relative configurations were established by means of 2D-NMR spectroscopy including COLOC and PSNOESY.
