Nowadays, medical technology is constantly advancing, but there are also new problems that arise. For example, when choosing these instruments, people may not know which one is more effective, or they may not be able to make decisions, or they may do more useless tests. However, inspection and shopping are different, so attention should still be paid. Next, the editor will take you to pay attention to a question: Do we still need to do four-dimensional ultrasound after doing three-dimensional ultrasound?
1. Conventional color ultrasound can achieve the purpose of examination. For example, if there are any special diseases found in general color ultrasound examination, then consider doing a four digit color ultrasound for examination and diagnosis. Guidance: Therefore, it is not necessary to do a four digit color ultrasound in your situation. Besides, four-dimensional color ultrasound costs more, it is better for the examination. If you do a general color ultrasound examination and it shows no problem, then there is no need to do it again. Doing a general color ultrasound again at six and a half months can exclude fetal malformation screening.
2. Both three-dimensional and four-dimensional color ultrasound can screen for abnormalities, and four-dimensional color ultrasound examination can dynamically observe the activity of the fetus. Guidance: Therefore, after undergoing three-dimensional color ultrasound examination, four-dimensional color ultrasound examination can be omitted. If there are no abnormalities in the fetus during prenatal screening, there is no need to worry. Continue to observe and undergo prenatal examination on time.
3. Ultrasound can only examine physiological indicators of the fetus, while ultrasound can detect its development by observing fetal behavior. Three dimensional and four-dimensional ultrasound can also provide more accurate basis for early diagnosis of congenital surface deformities and congenital heart diseases, such as cleft lip, spina bifida, brain, kidney, heart, skeletal dysplasia, etc. Many deformities that cannot be detected by ordinary ultrasound and ultrasound can be detected by three-dimensional or four-dimensional ultrasound, but the examination cost is relatively high. Generally, unless there are special circumstances, a regular ultrasound can be done. Let me give you a simple analogy about the difference between B-ultrasound and color ultrasound. It's like a book, where B-ultrasound can only see its outline, while color ultrasound can see the content of each page inside. Ultrasound and color ultrasound are the same thing. The first one was called ultrasound, which is black and white. Later, with scientific progress, it was made into color ultrasound (similar to black and white televisions and color televisions).
4. Ultrasound examination can have an impact on the fetus, but generally the examining doctor will take it into consideration during the examination process. Guidance: The angle and time of the inspection will be controlled within a range that does not affect the child, so you don't have to worry; The lump in your stomach may be caused by an allergy to the coupling agent used for the examination, and generally does not require medication. It will gradually recover.
The above is the information compiled by the editor regarding the question of whether or not to perform a four-dimensional ultrasound after undergoing a three-dimensional ultrasound. For some ordinary examinations, it is best to follow the doctor's arrangement and entrust the task of selecting medical equipment to the doctor. After all, most examination instruments are still convenient for doctors to diagnose, so there is no need for everyone to pay attention. I wish everyone good health.
