Plain-English summary
A group of 50 female dogs with mammary tumors underwent testing to see if a new imaging method called acoustic radiation force impulse elastography could help tell the difference between benign (non-cancerous) and malignant (cancerous) tumors. Traditional ultrasound didn't effectively separate the two types, but the new method showed promise. It found that malignant tumors had a higher shear velocity (3.33 m/s) compared to benign ones (1.28 m/s), suggesting it could be a useful tool for veterinarians in diagnosing mammary neoplasia. This could lead to better treatment decisions for dogs with these tumors.

Abstract
OBJECTIVES: To evaluate the applicability of acoustic radiation force impulse elastography as a complementary method in diagnosing mammary neoplasia in dogs. METHODS: Mammary tumours from 50 female dogs were evaluated and divided into two groups: G1 (benign tissue) and G2 (malignant tumours). The nodules were assessed by B-Mode ultrasonography, qualitative and quantitative acoustic radiation force impulse elastography and histopathology. RESULTS: B-Mode ultrasound examination was ineffective at separating the tumours into the two groups. Likewise, there was no correlation between the grayscale images of the mammary tissue by qualitative elastography. A difference was found in the deformity of the mammary masses between the malignant and benign groups (P = 0 · 002). Using quantitative elastography, the mean values of shear velocity were 3 · 33 m/s for malignant tumours and 1 · 28 m/s for benign tissue (P < 0 · 0001). CLINICAL SIGNIFICANCE: The use of acoustic radiation force impulse elastography may help to differentiate between malignant and benign mammary neoplasms.
