Abstract

Objective: To dynamic investigate the ring shape and flower crest shape CT enhancement in hepatic tumor. Methods: Observation of single-level dynamic computed tomography hepatic arteriography(SD-CTHA) so that analysis of image of SD-CTHA in hepatocellular carcinoma and hepatic metastases. Results: Sustained enhancement was noticed in tumor center and slowly diffused to tumor circumference after maximum contrast-enhancement, and flower crest shaped contrast-enhancement was formed while contrast agent was disappeared in hepatocellular carcinoma. Diffused enhancement was showed from tumor margin to center, slow and sustained enhancement in circumference was showed while contrast agent of the tumor center was disappeared after maximum contrast-enhancement in hepatic metastases. The time-intensity of ring shape enhancement was observed by Mann-Whitney method(P=0.000<0.01). Conclusion: SD-CTHA had diagnostic and differential diagnostic value in ring shape enhancement hepatocellular carcinoma and hepatic metastases.
