What can be detected by color Doppler ultrasound of lymph nodes

The human lymphatic system is the human immune system, which can clean up toxins ingested by the human body. Therefore, if people ingest too many toxins and the lymphatic system is overloaded, it may lead to the formation of lymph nodes. If the lymph nodes are relatively small, drinking more water will slowly make them disappear, but if the lymph nodes are enlarged, you need to go to the hospital for examination. So what can lymph node ultrasound detect?

Color Doppler ultrasound of the cervical lymph nodes will definitely only examine the lymph nodes, mainly to see whether the lymph nodes are enlarged. Lymph nodes are part of the lymphatic system, which is part of the body's immune system. If there is swollen lymph nodes, it cannot be ruled out that it is caused by a tumor or infectious disease. Lymph nodes collect lymph fluid from surrounding tissues. If there are inflammatory substances in the lymph fluid, it can cause inflammatory reactions in the lymph nodes. This may cause swollen lymph nodes.

How to check for cervical erosion

1. Gynecological examination: focus on checking the size, shape, texture, thickness of the cervical canal, and whether there is contact bleeding. Secondly, check the condition of the vulva, vagina, uterus and paracervical tissues such as the ovaries, fallopian tubes, pelvic lymph nodes, etc.

2. Cervical smear cytology is a routine gynecological examination. It is simple, easy, cost-effective, and the most important auxiliary examination and the preferred initial screening method for cancer prevention surveys.

3. Colposcopy can quickly detect lesions that are invisible to the naked eye. Taking biopsies from suspicious areas during colposcopy can significantly improve the accuracy of biopsies.

4. The iodine test and visual observation are very simple, inexpensive, and can detect at least 2/3 of the lesions. Currently, the World Health Organization (WHO) recommends the use of visual inspection in developing countries. As a preliminary screening method for cervical cancer, 3%-5% acetic acid solution is applied to the cervix to observe the reaction of the cervical epithelium to acetic acid.
