Can abdominal B-ultrasound check the cervix?

We all know that B-ultrasound is a very good clinical examination method, which can be used to discover some problems in the body. Especially for pregnant women, it is very important to have regular B-ultrasound. During the B-ultrasound process, pregnant women can see the actual development of the fetus, and even in the second half of pregnancy, they can see what the fetus is doing in the uterus. So, can abdominal B-ultrasound check the cervix?

Generally speaking, ordinary gynecological abdominal B-ultrasound examination cannot examine the cervix.

An abdominal B-ultrasound can generally check the uterus, ovaries, fallopian tubes, and pelvic cavity. It can determine the position and size of the uterus, the presence of uterine fibroids, the size of the ovaries, exclude ovarian cysts, whether there is pelvic fluid accumulation, etc. At the same time, it can detect the development of follicles and ovulation.

In special circumstances, B-ultrasound can be used to examine the cervix. Especially in the field of obstetrics, when the length of the cervix needs to be measured, B-ultrasound can be used to determine the length and thickness of the cervix in order to clarify the condition and function of the cervix. At this time, B-ultrasound examination is convenient, fast and accurate. Especially for some special patients, such as those with cervical trauma, or a history of cervical surgery, or those who have undergone cervical conization, in the late stages of pregnancy, B-ultrasound examination is used to determine the condition of the cervix. It is convenient, non-traumatic, can be used repeatedly, and is widely used clinically.

However, in some cases, B-ultrasound examination cannot examine the cervix.

For example, it is necessary to check the condition of the cervical surface, whether the cervix is ​​smooth, whether it is eroded and the degree of erosion, etc., which cannot be diagnosed by B-ultrasound. Especially if you want to do a cervical cancer screening, B-ultrasound cannot be used for the examination. At this time, a gynecological examination, as well as cervical TCT and HPV screening are needed. Ultrasound examination is powerless.

Therefore, B-ultrasound examination of the cervix has its limitations. It can only be used in obstetrics to examine the length and thickness of the cervix, but cannot examine the surface of the cervix, cannot determine the condition of cervical lesions, and cannot perform cervical cancer screening.
