The univariable analysis of quantitative parameters showed that T1rt-HBP had the best efficiency for predicting CK19-positive HCCs, possibly because the T1 relaxation time was proportional to the concentration of gadolinium contrast agent, and more gadolinium contrast agent enters the tumor tissue at the HBP, thereby shortening the T1 relaxation time. The gene discussed is KRT19; the disease is neoplasm.
