Advantages and disadvantages of ultrasound at 37 weeks of pregnancy

We all know that it is very difficult for every pregnant mother to be pregnant for ten months, and our mothers have to endure the physical discomfort, so we should take better care of our pregnant mothers. Many people know very little about B-ultrasound during pregnancy. We must know more about this aspect, so that it can bring greater help to the health of our pregnant mothers. I believe everyone is very interested in the content of B-ultrasound at 37 weeks of pregnancy. Let us learn about it together!

Pros and Cons:

Advantages of B-ultrasound examination of the liver:

1. Ultrasound examination is a non-radiation-damaging examination, which is its biggest advantage compared with CT and is a non-invasive examination technology.

2. Since the ultrasound probe can be placed at will, cross-sectional images in various orientations can be obtained, and the lesions can be located and measured based on the characteristics of the sonogram. Real-time dynamic display can be used to observe the hemodynamics of the liver.

3. Ultrasonic examination can obtain examination results immediately and can be repeated for observation many times.

4. Ultrasound examination equipment is relatively light and easy to operate compared to CT and other equipment, and can be used for bedside examination of critically ill patients.

Disadvantages of B-ultrasound examination of the liver:

1. Sonograms show changes in the acoustic impedance difference of organs and tissues and lack specificity. Qualitative diagnosis of lesions requires comprehensive analysis and combination with other imaging manifestations and clinical data. In other words, B-ultrasound examination of the liver cannot generally be used as the sole evidence to diagnose a disease.

2. The sonogram shows a local cross-section, and it is difficult to clearly display the spatial position and configuration of the liver and lesions as a whole in one image. In addition, if the lesion is too small or the acoustic impedance difference is not large and does not cause reflection, it will be difficult to display on the sonogram.

3. The accuracy of B-ultrasound liver examination results is closely related to the performance of the ultrasound equipment and the operating skills and experience of the examiner. It is an operator-dependent technology. What this sentence means is that the accuracy of B-ultrasound examination has a lot to do with the operating level of the doctor doing the examination.

The above content introduces us to some relevant information about B-ultrasound at 37 weeks of pregnancy. I believe that everyone now has a clearer understanding of the content of this cake. We should try to learn more about this aspect to help our pregnant mothers give birth to our babies better.
