The article was professionally consulted with resident doctor Nguyen Quynh Giang - Department of Diagnostic Imaging and Nuclear Medicine - Vinmec Times City International General Hospital.Ultrasound is an indispensable imaging tool in clinical practice in all specialties. 2D ultrasound is an easy-to-implement imaging tool that is highly effective in diagnosing many diseases. Especially in the field of obstetrics, 2D ultrasound is a means to help monitor the health status of the fetus. So what's wrong with continuous 2D ultrasound?
1. What is an ultrasound?
Ultrasound is a non-invasive technique in diagnostic imaging, which is very commonly used for diagnosis and treatment in medicine today in all specialties. Ultrasound technology provides structural images by rendering structures inside the body based on the reflection of high-frequency sound waves of tissues, thereby describing normal or abnormal characteristics of the tissue. , organs in the body that cannot be observed.2D ultrasound or 2D ultrasound is a form of ultrasound that gives black and white images by moving the transducer on the patient's skin, allowing to record the sound structure of tissues in the body lying on the scanning plane of the patient. beam of sound waves, this is the method of ultrasound tomography. The image obtained from these echoes will be stored in memory and converted into a signal on the transmission screen by black and white, gray dots.

2. Purpose of Ultrasound
Ultrasound is used to examine the structures and organs of the body: Most of the components of the abdomen or abdominal cavities, the digestive system, appendix, colon, liver, spleen, pancreas, biliary tract, and gallbladder. ..., obstetrics, cardiology, urinary system, prostate gland, thyroid gland, mammary gland, musculoskeletal, tendon attachment points, testes, uterus, ovaries... site for biopsies, intra-articular injections, vascular access and support for a number of other invasive techniques. Therapeutic ultrasound based on the effect of radiofrequency waves for some rehabilitation specialties.3. Is continuous 2D ultrasound okay?
2D ultrasound is a form of ultrasound that shows black and white images, and has the same level of detail as a film negative. Ultrasound is widely used, simple and inexpensive in imaging techniques.Is the continuous ultrasound okay?. Most ultrasound methods are non-invasive and usually cause no pain or discomfort to the patient. Ultrasound does not adversely affect the body and health because it does not use radiation like X-ray techniques, computed tomography... Therefore, it is possible to perform continuous ultrasound at the necessary level for monitoring and treatment.
There are many opinions that 2D ultrasound is an outdated ultrasound method, so the ultrasound image is blurry, so it doesn't have high accuracy. However, through many studies by many specialized experts, 2D ultrasound is completely accurate and has the same value as the most advanced types of ultrasound today, 3D and 4D ultrasound. The importance of accuracy in 2D fetal ultrasound is the skill of each expert, equipment, and technician when participating in the ultrasound process for pregnant women.
For obstetrics, ultrasound is usually conducted at different times in pregnancy, usually 3 times in 1 month, so it does not cause any effect, the ultrasound wavelength is also small and does not cause any harmful effects. harmful.

4. Limitations of 2D . ultrasound
Ultrasound propagates less in the gaseous environment, so it is difficult to examine hollow organs such as intestines, stomach and organs that are obscured by stomach and intestines such as pancreas, aorta... Need to coordinate with other methods. other diagnostic facilities. Patients who are overweight, obese, and have a large waist circumference will lead to more difficult ultrasound, so it is necessary to combine other imaging techniques such as X-ray, computed tomography with or without contrast, and magnetic resonance may be more effective. 2D ultrasound is more limited than 3D, 4D ultrasound in certain diseases Although ultrasound is an objective imaging technique, it requires a lot of experience. For a fetal ultrasound, there may be slight discomfort when the transducer is placed on the abdomen or in the vagina or anus. Vinmec International General Hospital offers a Package Maternity Care Program for pregnant women right from the first months of pregnancy with a full range of antenatal check-ups, periodical 3D and 4D ultrasounds and other routine tests to ensure that the mother is healthy and the fetus is developing comprehensively. Pregnant women will no longer be alone when entering labor because having a loved one to help them during childbirth always brings peace of mind and happiness.For detailed information, please contact the hospitals and clinics of Vinmec health system nationwide.
