For women who are pregnant, ultrasound examination is indispensable. Through ultrasound examination, the obstetrician and gynecologist can observe the position, development form, heartbeat and other conditions of the embryo.
How long after ultrasound pregnancy can I do it? Is it harmful to babies?
Generally speaking, the first B-ultrasound examination of pregnant women will be carried out in the first 3 months of pregnancy, and the best time is about the 8th week, when the baby can be found in time through B-ultrasound whether the baby will have ectopic pregnancy, hydrocephalus, stillbirth and other abnormalities.
As for whether the B-ultrasound examination is harmful to the fetus, from the principle of the examination, the B-ultrasound belongs to high-frequency non-destructive sound wave conduction, which does not produce electromagnetic radiation and ionizing radiation, so it will not cause any tissue damage to pregnant women and fetuses.
In addition, there is no evidence at home and abroad that ultrasound diagnosis will have adverse effects on subjects.
In summary, pregnant women do not have to worry too much, as long as they follow the advice of professional doctors and the frequency of examination, it is safe to use B-ultrasound examination reasonably.
These 5 types of diseases can also be screened by ultrasound
B-ultrasound, as a non-invasive medical imaging method, is not only suitable for pregnant women, but also clinically widely used in many disciplines. Here are some common types of diseases that ultrasound tests can use to look for:
1. Liver-related lesions
Through liver ultrasound examination, doctors can find liver lesions in the patient's body in a timely manner, including liver cysts, liver stones, cirrhosis, chronic hepatitis and so on.
2. Thyroid-related lesions
Ultrasound examination can assist in the diagnosis of thyroid diseases such as thyroid nodules and thyroid cysts.
3. Heart-related lesions
Cardiac ultrasound is mainly used clinically to check the beating of the heart and blood flow. Especially for middle-aged and elderly people, B-ultrasound examination is very valuable, which can help diagnose myocardial ischemia, hypoxia, thrombosis and other dangerous cardiovascular diseases.
4. Kidney-related lesions
Renal ultrasound can generally check kidney activity, renal effusion, kidney stones and other problems.
5. Gynecological-related lesions
Lesions in the pelvis, uterus, ovaries and other parts of women can also be judged by ultrasound examination. Common things like endometriosis, ovarian cysts, uterine fibroids, etc. can be detected during the examination.
Ultrasound is not a panacea, and these fetal abnormalities cannot be detected
B-ultrasound is a very commonly used fetal examination method, which can help diagnose a variety of fetal abnormalities, but not all fetal abnormalities can be completely detected by B-ultrasound. Like hearing impairment, congenital heart disease, gastrointestinal obstruction, congenital metabolic abnormalities, water brain and other abnormal conditions, B ultrasound can not be detected.
Clinically, although ultrasound can provide a lot of information about fetal development and structure, some fetal abnormalities may require other examination methods, such as amniocentesis and chorionic biopsy, for further diagnosis.
In addition, the type of fetal abnormality and the severity of the abnormality will also affect the detection rate of ultrasound items. Some fetal abnormalities may be difficult to detect in the early stages and require follow-up examinations. Therefore, if there is a risk or concern about fetal abnormalities, your doctor may recommend other, more specific tests to make an accurate diagnosis.
