Anechoic breast nodules

Most people use ultrasound to check for foreign bodies in the body, and the main result reflected by ultrasound is echo. The echo can show different grayscale conditions depending on the shape and size of the foreign body. If a woman finds that she has a problem with her breast or has a breast nodule, she can go for an ultrasound examination. But after the ultrasound examination, she finds that there is no echo. What's going on?

Why are breast nodules without echo?

First of all, we need to understand what echo is. Echo actually represents the intensity of different gray levels in the image. Generally, it is divided into low echo, strong echo, equal echo, high echo and no echo. No echo indicates a cystic condition, that is, the presence of liquid inside. Low echo generally appears as a dark horizontal echo. High echo means that the reflection coefficient is greater than about 20%, the grayscale is relatively bright, and there is no sound shadow behind it.

When patients with breast nodules undergo B-ultrasound examination, they can find low-echo nodules in their breasts. The boundaries of the nodules are relatively clear, and the echoes are relatively uniform. There is no blood flow. Such nodules are generally caused by breast hyperplasia or small fibroadenomas. The fat tissue in the gland will also show such low echoes, and it is generally impossible to distinguish them through B-ultrasound examination. If the shape of the low echo is irregular and the boundary is unclear, but the blood flow signal is very rich, breast cancer cannot be ruled out, so it is best to do a biopsy for a clear diagnosis.

What's the matter with breast nodules being echo-free? If breast nodules are echo-free, it means that they are cystic, that is, there is fluid inside. In addition to echo-free, there may also be low echo and high echo. Different echo conditions indicate that the patient's condition is of different severity.
