ultrasound images of animal breast cancer using veterinary B-ultrasound machine

① Solid nodules or tumors in the glandular layer of animal mammary glands, most of which are 1-3 cm.

② The boundary of the veterinary B-ultrasound machine image is unclear and irregular, and crab-like changes can be seen extending to the surrounding tissues. When invading along the duct, cord-like or axon-like changes can be seen on the nipple side.

③ The veterinary B-ultrasound machine often shows low or extremely low echoes, which may be uneven. When there is liquefaction necrosis, echo-free cystic changes can be seen.

④ In the central or eccentric part of the veterinary B-ultrasound machine image, different numbers of dots or small, irregular strong echoes can be seen, and the sound attenuation behind represents tumor calcification.

⑤ The echo of the posterior wall or the back is reduced or irregular sound shadows are seen on both sides.

⑥ The surrounding tissue is thickened, and the veterinary B-ultrasound machine shows a strong echo halo, which is consistent with the inflammation of the stromal tissue around the tumor in pathology, and some may also be caused by the burr-like extension of the tumor to the surrounding area.

⑦ Invade the skin forward, causing the latter to thicken, and invade backward, and may be adhered and fixed to the pectoral muscle. ⑧CDFI shows: increased blood flow in the tumor, in the form of dots or rods, and some are more typical, twisted or serpentine blood flow;

⑨Special cases: The boundaries of medullary carcinoma and mucinous carcinoma can be relatively clear and regular, and echo enhancement can often be seen in the back. ⑩Difficulty: For some nodules smaller than 1cm, the above signs are atypical; the detection rate of multifocality is not high.

①Most lesions are difficult to display because they are too small, and can only be displayed when they are larger (greater than 3-5mm).

②Mostly occur in the central lactiferous duct and lactiferous sinus. Low, medium or strong echo nodules can be seen protruding into the lumen in the localized dilated duct, and the distal duct often dilates.

③Sometimes the duct dilates into a cystic shape, which forms a cystic and solid mass with the nodule.

④Sometimes the proximal duct can also dilate.

⑤CDFI shows that there is usually no blood flow in the tumor. If blood flow signals are found, it may be a malignant transformation.
