The difference between intracavitary color Doppler ultrasound and vaginal Doppler ultrasound

Many people do not have a special understanding of intracavitary color ultrasound and vaginal ultrasound. Women often undergo color ultrasound examinations when they are pregnant. Depending on different situations, intracavitary color ultrasound or vaginal ultrasound examinations are needed. The first thing to understand is that vaginal ultrasound requires a tube to be inserted into the vagina for examination. These examination sites are different, and the examination items will also be different. Let’s take a look at this aspect.

The difference between intracavitary color Doppler ultrasound and vaginal Doppler ultrasound

1. Vaginal ultrasound has a wider range of examination than color Doppler ultrasound

First of all, everyone should understand that color ultrasound is an upgraded version of ordinary B-ultrasound. Ordinary B-ultrasound is a black and white image and can only see limited information. As the name suggests, color ultrasound is a colorful image. The observed image is mainly red and blue. The side facing the probe appears red, and the opposite side appears blue.

Color ultrasound can detect many more problems than ordinary B-ultrasound and is more accurate. Generally, color ultrasound is enough for female friends to have a gynecological examination, but if you want to check for gynecological cancer, tumors, etc., a more accurate examination, namely vaginal ultrasound, is still needed.

2. Different inspection sites

Vaginal ultrasound is a vaginal B-ultrasound, in which the ultrasound probe is placed in the vagina or rectum (anus) for examination. For women who have had sexual life, the examination can be performed through the vagina, and for women who have not had sexual life, the B-ultrasound examination can be performed through the rectum. Color ultrasound, like ordinary B-ultrasound, moves the probe directly on the abdomen. Most people are more accepting of abdominal B-ultrasound because many doctors who perform vaginal B-ultrasound are rather rough and painful, and women are more shy and find it difficult to relax during the examination.

3. Vaginal ultrasound does not require holding urine

Because vaginal ultrasound involves placing the B-ultrasound probe in the vagina or rectum (anus), there is no need to drink a lot of water like with color ultrasound, and you don’t need to fill your bladder completely before the examination. And because it is close to the uterus and ovaries, the images are clear and have high resolution, so the results of transvaginal ultrasound examination are more accurate.

4. In many cases, transvaginal ultrasound cannot be performed

Color ultrasound is relatively easy to do. As long as you can hold your urine successfully, you can do it whenever you want. However, transvaginal ultrasound cannot be performed in many cases.

Vaginal ultrasound is not suitable for those who are bleeding, those with infectious diseases such as vaginitis, sexually transmitted diseases, other cervical diseases, vaginal diseases and some vulvar diseases, in order to prevent infection, cross-infection and bleeding and other adverse consequences.

The difference between abdominal B-ultrasound and vaginal ultrasound

Vaginal ultrasound, also known as vaginal B-ultrasound, also known as intracavitary B-ultrasound, is a method of ultrasonic diagnosis by inserting the B-ultrasound probe into the vagina or rectum. It is particularly suitable for observing pelvic organs in the small pelvis.

B-ultrasound vibrates 20,000 to 1 billion times per second. Sound waves that are inaudible to the human ear are called ultrasonic waves. The imaging discipline that uses the physical properties of ultrasound for diagnosis and treatment is called ultrasound medicine. It has a wide range of clinical applications and has become an indispensable diagnostic method in modern clinical medicine.

Vaginal ultrasound is performed through the vagina and mainly looks at the pelvic cavity, which is relatively clear. B-ultrasound is in black and white and can be viewed anywhere.

For most women, color ultrasound is a relatively suitable detection method. However, if a woman wants to carefully check the pregnancy status in her body, it is not impossible to do a vaginal ultrasound. However, vaginal ultrasound cannot be done in many cases. Pregnant women must pay attention before doing a vaginal ultrasound. Pregnant women should discuss the specific situation in detail with the doctor and follow the doctor's advice.
