Abstract:
Objective To compare the hemodynamics features of recurrent hepatocellular carcinoma between contrast-enhanced ultrasonography (CEUS) and contrast-enhanced MRI (CEMRI).Methods Forty three recurrent hepatocellular carcinoma lesions in 39 patients were evaluated by CEUS and CEMRI.All lesions were proved by operation or needle biopsy.The dynamic enhancement and washout process on CEUS and CEMRI were analyzed.Results On both two methods,all lesions showed hyperenhancement.Among which,30.2％ (13/43) lesions showed hyperenhancement during arterial phase and no washout was found during portal venous phase,37.2 ％ (16/43) lesions hyperenhanced during arterial phase and washout during portal venous phase.During late phase,the enhancement of 60.5％ (26/43) lesions decreased and 7.0％ (3/43) lesions showed no washout on CEUS or CEMRI.The overall concordance ratio between two methods was 67.4％ (29/43).Difference of hemodynamics features between CEUS and CEMRI was not statistically significant.Conclusions CEUS can accurately display the hemodynamic features of recurrent hepatocellular carcinoma,and enjoy high consistence with CEMRI.
