The aim of the study was to evaluate the ultrasonographic appearance of canine mammary gland tumours on B-mode, colour flow Doppler and strain elastography, and to determine a cut-off value for strain ratio, which could serve as an indicator of malignancy. The study was performed on a total of 12 animals which were presented with masses of the mammary glands. They were subsequently divided into two groups of six each - group I (benign) and group II (malignant), based on histology. Numerous qualitative and quantitative parameters were analysed, of which strain ratio showed a highly significant correlation with malignancy. The results revealed that a strain ratio cut-off of e”1.68 was positively correlated with malignant mammary tumours. The study showed that ultrasonography could be used as a non-invasive, pre-operative measure of malignancy though further research with larger sample populations are warranted to confirm the findings.
