Abstract:
Objective Using coded harmonic angiography to observe hepatocellular carcinoma blood perfusion features,further assess this modality clinical value in qualitative diagnosis of liver malignant tumor.Methods Through left forearm vein bolus injection of fluorine-carbon contrast agent,35 patients with 41 hepatocellular carcinoma lesions were examined with coded harmonic angiography,intratumoral vessel enhanced time,vascularity,blood perfusion were observed.All patients were simultaneously videotaped before and after contrast.Results It was about 15～20 s after the injection of contrast agent when the enhancement of tumor had just commenced,peak time about 60～90 s and persistence time about 240～300 s.Lesions were more obviously enhanced than normal liver tissue,several tumor vascularity was displayed from border to center,contrast agent gradually centripetal filled-in,formed "weeping-willow" echo.Pressed and rimlike peripheral vessel developments were earlier than normal liver tissue.Conclusions Coded harmonic angiography could real-timely display hepatocellular carcinoma blood perfusion,which has an important clinical value in qualitative diagnosis of liver malignant tumor.
