B-mode mammary ultrasound (between markers) of cats with mammary tumors during anestrus. (a) Left caudal abdominal mammary gland with hypoechoic parenchyma, poorly defined margins, and uneven edges. (b) Right cranial abdominal mammary gland with heterogeneous echotexture, uneven shape, unclear edges, and the presence of several lobulations. (c) Left caudal abdominal mammary gland with anechoic content and hypoechoic intratumoral sediment and well-defined margins, creating acoustic enhancement (AE). Cr: cranial. Frequency = 15 MHz.
