title: The echogenicity of hypervascular areas in liver tumours. An in vivo study.
abstract: The ultrasound images of liver tumours of 28 patients were compared with their vascular images on arteriography. In addition, 17 of these patients underwent contrast computed tomography examinations, and a comparison was made between the markedly contrast-enhanced tumour areas and their ultrasound images. No clear correlation was found between the echogenicity of the tumours and the vascularity seen in arteriography and/or computed tomography. The hypervascular and hypo- or avascular tumour areas could be markedly or minimally echogenic or show only diffuse alteration in the echo architecture.
