title: Application of shear wave elastography in the diagnosis of mammary gland neoplasm in dogs.
abstract: The aim of the study was to evaluate the usefulness of elastography in the differential diagnosis of benign and malignant tumours of the mammary gland in dogs. The study was performed to 12 female dogs of different breeds aged 5-12 years in which tumoral lesions of the mammary gland were found in the clinical examination. In all the animals elastographic examination of the lesions was carried out and then the fine-needle aspiration biopsy was performed to determine the nature and degree of malignancy of the lesions. The examinations proved that benign neoplasms of the mammary gland showed low stiffness (average 22.42 kPa, range 19 to 42.4 kPa), whereas malignant neoplasms were characterized by high stiffness (average 235.44 kPa, range 171 to 300 kPa). On the basis of the results obtained we conclude that the elastography of proliferative lesions of the mammary gland is a useful diagnostic method for distinguishing benign neoplastic lesions from malignant neoplasms.
