NQO1 and hepatocellular carcinoma: Finally, six parameters from preoperative arterial CT images (Whole_glszm_SmallAreaEmphasis, Whole_ngtdm_Coarseness, Whole_peri_glrlm_RunLengthNonUniformity, Whole_peri_ngtdm_Coarseness, Whole_peri_firstorder_TotalEnergy, and Whole_peri_glszm_SmallAreaLowGrayLevelEmphasis) were included to establish a bi-regional model that could accurately predict the higher expression levels of NQO1 in patients with HCC, with an AUC of 0.9079.
