[Imaging tumor vascularization of hepatocellular carcinoma with ultrasound angiography].

AIM

With the introduction, in 1994, of Ultrasound Angio (UA), a technical innovation in sonographic colour coded blood-flow detection has become available using angle-independent amplitude signal plotting leading to an enhanced sensitivity in blood flow detection.

METHOD

In a first application study we attempted to verify an improved blood-flow detection in hepatocellular carcinomas (HCC) compared to conventional colour coded duplex sonography.

RESULTS AND CONCLUSION

In all patients with HCC we found a highly improved detection of internal vascularity. In one patient, we could even detect blood flow in the tumour which was not visible with several other conventional highly sensitive colour duplex equipment.
