Understand the text, what can be checked by ultrasound?
Not all systems can do ultrasound examination. Therefore, according to the function of ultrasound probe, there are roughly classified as: superficial organ ultrasound examination, cardiovascular and extremity blood vessel ultrasound examination, abdominal organ ultrasound examination, and obstetrics and gynecology ultrasound examination.
Which parts of the superficial organs can be examined by ultrasound?
Thyroid, breast, salivary glands, lymph nodes, superficial masses, muscles, nerves, and joints are collectively referred to as superficial organs. Superficial ultrasound is the first choice for finding lesions such as tumors and inflammation in them. It can be based on the various ultrasound manifestations of the lesions. The characteristics determine the nature and source of the disease.
Children with open fontanelle within 2 years of age can observe the changes in the ventricle structure of the child through the small passage of fontanelle or temporal window (commonly known as the temple). Ultrasound examination has gradually become the main method of neonatal brain examination.
Musculoskeletal ultrasound is a newly emerging examination item in recent years. The application of high-frequency ultrasound probes has achieved the goal of clearly displaying the superficial soft tissue structures of human muscles, tendons, ligaments and peripheral nerves. At the same time, it can also determine whether these structures are affected by external forces. Sports lesions.
What can be seen in an ultrasound examination of the cardiovascular system?
Ultrasound can observe the position of the heart, measure the size of each ventricular cavity, evaluate the function of the heart and the state of blood flow in the heart cavity. You can observe the course of the large blood vessels connected to the heart, the origin, thickness, hardening and blood flow of the blood vessels, and judge the degree of stenosis. You can also observe the internal structure of the arteries and veins of the head, neck, trunk, and extremities, the internal structure of the veins, the thickness of the lumen, the direction of blood flow, the speed of blood flow, and other conditions.
Which parts of the chest and abdomen can be examined by ultrasound?
Ultrasound can clearly show the effusion in the thoracic cavity and evaluate the amount of effusion, observe the degree of lung consolidation and whether there is a space, and can also be used to guide the process of diagnostic puncture or treatment.
Abdominal ultrasound can examine the solid and hollow organs of the abdomen.
Substantial organs include liver, pancreas, spleen, kidneys, prostate, etc. Observe the appearance, internal changes of various organs and their relationship with surrounding tissues, and observe structural changes to determine whether the organs have inflammation or Diseases such as tumors.
The cavity organs refer to the stomach and intestines. During the inspection of the cavity organs, gastrointestinal visualization aids need to be taken to eliminate the interference of gas and mucus in the stomach and intestines. When the gastrointestinal visualization aids fill the entire stomach, It is possible to find lesions such as tumors or gastric ulcers.
Ultrasound can detect the gallbladder, bladder and other fluid-containing organs in the abdominal cavity with high clarity and accuracy. For example, gallbladder stones, gallbladder tumors, bladder stones and bladder masses can be accurately detected.
What can be seen in gynecology and obstetric ultrasound examinations
Ultrasound can observe the female pelvic organs through the abdomen or vagina. The main organs of the female pelvic cavity are the uterus and ovaries. Ultrasound is the first choice for gynecological examinations. Transabdominal ultrasound needs to hold back urine, while transvaginal ultrasound does not need to hold back urine and is more accurate. It can find "small lesions".
As a special inspection group, pregnant women have strict requirements on inspection methods, and the advantages of ultrasound non-invasive and repeatable operation make it the main preferred inspection method for fetal malformation screening. Prenatal ultrasound can see all stages of the fetus. Growth and development, accurately find out whether the fetus is abnormal.
In short, conventional ultrasound examination is non-invasive, non-radiation, convenient, inexpensive, and has a wide range of applications. It is the first choice for clinical examination of diseases and is known as one of the "three routines".
