Gadoxetic acid-enhanced magnetic resonance imaging (MRI) has been widely used in detection and diagnosis for hepatocellular carcinoma (HCC), while transient severe motion artifact that affects the arterial phase (AP) images quality and reduces diagnosis performance remains a concern. A new diagnosis criterion for HCC integrating CTAP and MRAP images was introduced in this study and achieved a high sensitivity and comparable specificity when compared with the gadoxetic acid-enhanced MRI only. It may be able to improve the diagnostic performance of gadoxetic acid-enhanced MRI in patients with HCCs and further affect the clinical treatment plan.
