What can B super check? Is B-ultrasound harmful to human body? Do you need to urinate for B-ultrasound? For B-checks, you need to understand these three common-sense questions.
　　 First, what can B check?
In the case of pregnant mothers, B-ultrasound can check the condition of fetal development, so what can B-ultrasound check out for ordinary people? Let's understand!
1, B-ultrasound can check the size, location, shape of the uterus and ovary with or without dysplasia, the presence or absence of tumors and the relationship between the tumor and the uterus and ovary; can detect abnormal effusion in the pelvic cavity; there is no foreign body in the uterine cavity.
For obesity, abdominal wall tension, especially unmarried women or infants, when the pelvic conditions can not be found, B-ultrasound can be used for examination.
2, B super can quickly check the size and shape of the liver, gallbladder, bile duct, spleen, pancreas, kidney, adrenal gland, bladder, prostate and other organs; whether it is in a normal position; whether it is oppressed by surrounding tumors or organs .
At the same time, it can accurately determine the location of the tumor in the abdominal cavity and the relationship with the surrounding organs; can accurately distinguish whether the tumor is substantial or liquid cyst, hematoma and abscess; can also identify whether the tumor is benign or malignant of.
3, B super can accurately determine whether there is ascites in the abdominal cavity, even a small amount of ascites can be measured with B-ultrasound; can detect abdominal lymph nodes, more than 1 cm in the pelvic swollen lymph nodes; can observe the gallbladder contraction, make gallbladder function judgment.
　 Second, is B-ultrasound harmful to human body?
Ultrasonic is a high-frequency sound wave. It is not radioactive. It is safe and harmless to human body. It is widely used in various organ systems and prenatal testing of the fetus. It is also very safe for pregnant women. Ultrasound has become one of the first choices for clinical examination.
　　 Third, do you need to urinate for B-ultrasound?
Gynecological B-ultrasound is mainly divided into two types, one is a transabdominal B-ultrasound that requires "sputum urine", and the other is a transvaginal B-ultrasound that does not "urine".
The uterus and ovaries are deep inside the pelvis, and the small intestine tends to sag into the pelvic cavity. When the abdomen B is overtime, the peristalsis of the intestine and its contents interfere with the image of the uterus and ovaries, making it unclear. Therefore, a large amount of drinking water is needed before the examination to fill the bladder and push the intestines upward. If the bladder is not filled, an ultrasound examination will cause the gas in the bladder to overlap with the gas in the uterus, causing misdiagnosis and missed diagnosis. But not all gynecological transabdominal B ultrasound needs to urinate, such as the following situation is completely unnecessary: ​​after 8 weeks of pregnancy, the uterus grows into the abdominal cavity, the intestinal tube is naturally pushed upwards, and there is amniotic fluid in the uterine cavity. At this point, the fetus is no longer needed to observe urine.
