| Abstract: | Objective To investigate the correlation of hepatocellular carcinoma (HCC) examined by dynamic contrast-enhanced (DCE) MRI with the degree of cellular differentiation and the size of focal lesions. Methods The scanning patterns of the different phases of DCE MRI of 46 cases of HCCs confirmed by pathology after operation were studied. The enhancement of HCCs in the arterial phase was analyzed according to the degree of pathological differentiation and the size of focal lesions. The collected data were analyzed by statistics. Results The increasing pattern of the scanning enhancement in the arterial phase of DCE MRI of HCCs was shown as worse differentiation and larger size of HCCs. Conclusion Dynamic contrast-enhanced MRI of provides a method for studying the blood dynamics of HCCs. |
