Numbers in parentheses are percentages.

¹The difference between peripheral nodular,Mosaic/chaotic enhancement and feeding artery of CPI patterns were observed (P < 0.001, P < 0.001, P = 0.010) in staff group and (P = 0.001, P < 0.001, P = 0.021) in resident group. CPI: Color parametric imaging; H: Hemangioma; M: Metastasis.
