What you need to know about ultrasound？
1. Ultrasound of the abdomen.
Abdominal ultrasound is the most common and is usually what we call an examination of the liver, gallbladder, pancreas and spleen. It is suitable for: abdominal screening for abdominal pain, bloating, abdominal discomfort and other abdominal screening and examination specifically for an organ disease.
Requirements: fasting for at least 8 hours. Fasting means not eating anything and not drinking anything. Usually, we often encounter patients who say they have not eaten anything, and then press them again will tell you that they drank some milk, or drank a bowl of soy milk. (Of course, if you need to take medicine, you can drink a little water).
2. Urological ultrasound.
Urological ultrasound includes examination of both kidneys, ureter, bladder, male plus prostate. It is mainly applicable to the screening of tumors, stones, developmental abnormalities of the urinary system as well as abnormalities found in urinary routine.
Requirement:Simple kidney examination can be done without preparation. The bladder, ureter and prostate need to be filled with bladder. You can drink 1000 to 1500 ml of water (or various drinks) 1 to 2 hours before the examination.
3. Obstetrics and gynecology ultrasound
Gynecologic ultrasound includes: examination of the uterus, bilateral ovaries and adnexal areas. It is mainly used for: tumors, developmental abnormalities, inflammation, early pregnancy (both intrauterine and extrauterine) of the gynecological system and general screening related to women of childbearing age.
There are two types of gynecologic ultrasound commonly used nowadays: transabdominal ultrasound and transvaginal ultrasound.
Transabdominal ultrasound requires: a full bladder. Most people have to hold it until they can't hold it. The sonographer will often ask: Can you hold it for a little longer? If you can, please continue to hold it for the best results.
Transvaginal ultrasound requires: Emptying the bladder. You need to empty your urine as much as possible before the exam. Yes, it is the opposite of transabdominal ultrasound.
In special cases, a combined scan of the above two modalities may be performed, and this is when our sonographer will tell you what to do.
Obstetric ultrasound: It is mainly used to monitor the growth and development of the fetus in all periods and to screen for fetal malformations.
Requirements: No special preparation is needed for obstetrical examination above 3 months of pregnancy, but in case of suspected placenta praevia in the middle and late pregnancy, it is still necessary to drink water to fill the bladder before doing the examination.
4. Cardiovascular ultrasound examination
Cardiovascular system includes: heart, large blood vessels and peripheral blood vessels. Cardiac ultrasound is mainly used to diagnose heart diseases by scanning the heart structure, function and hemodynamic conditions. Vascular ultrasound mainly diagnoses vascular diseases by scanning the blood vessel wall, lumen and hemodynamic conditions.
Examination requirements: generally no special requirements.
5. Small organs and superficial ultrasound examination
Small organs include: thyroid, breast, parotid, submandibular gland, lymph nodes and other glands.
Superficial mainly refers to the mass that you can feel different from the normal tissue, in layman's terms, you feel like you have a growth on the surface of your body.
There is also a more specific examination: male examination, including testicles, epididymis, scrotum and penis.
Requirements: No special preparation is needed for this type of examination.
6. Emergency ultrasonography
Emergency examination is expensive in terms of time and finding the main cause of the disease, so emergency patients do not need to make preparations, but because the examination conditions are limited, there may be occasional discrepancies with your usual examination, such as missing small cysts, polyps and so on, which is understandable.
