[The echo-dense edge and hyper-reflective spikes: sensitive criteria for malignant processes in breast ultrasound]

At the Department of Gynaecology of the RWTH-Aachen, 110 patients with palpatory and/or mammographic suspect findings were sonographically examined. By using a high resolution 10 MHz-probe with a freely mobile transducer, a new method of differential diagnostic criteria was established, pertaining to the edge of the tumour. The high echogenetic halo and the hyperdense spikes proved to be most important differential diagnostic tools in assessing sonographically suspect tumours.
