Abstract:
Objective To investigate the role of new contrast agent and real time gray scale contrast tuned imaging in the evaluation of the perfusion and echogenicity of liver neoplasms and to discuss the diagnostic value.Methods Thirty five patients with unconfirmed liver neoplasms were enrolled in the study.Nine of them were diagnosed clinically,while the other 26 cases with pathological evidence through surgery or needle biopsy.Contrast agent SonoVue,Technos DU6 and CnTI technology were used.The contrast agents were delivered intravenously or through bolus injection.Results Timing of all phases following contrast injection in normal and cirrhotic liver was observed.And then the perfusion processs of liver neoplasms was recorded.Among the 23 cases of typical hepatocellular carcinoma(HCC),21 cases(91%) presented with early artery enhancement and immediate wash out,while the other 2 cases of small(
