IMAGING OF TUMOR VASCULARIZATION OF HEPATOCELLULAR CARCINOMAS VIA 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 hghly 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 equipments.
