Many people have experienced 4D movies, which can enjoy stereoscopic images and real-time experience of storms, smoke, and rain. Do you know the application of 4D technology in reproductive medicine? How much contribution does man make to mankind? Xinmin Health invited Professor Lei Kairong, director of the Department of Ultrasound Medicine at Yangpu Hospital (Shanghai Yangpu District Central Hospital) of Tongji University to introduce the four-dimensional uterine fallopian tube ultrasound contrast technique to the readers, hoping to bring inspiration and help to some women with difficulty in conception.
Break through traditional four-dimensional ultrasound technology
Ultrasound technology is an important basis for medical diagnosis. It is simple, dynamic, real-time, safe, non-invasive, non-radiative and repeatable. With the development of science, in recent years, four-dimensional ultrasound technology imaging is more clear and easy to distinguish, realistic and objective. It can observe human tissue structure and functional status in real time, and become one of the most commonly used and most important imaging examination methods in clinical practice.
There are many symptoms of female infertility, such as endometrial polyps, endometrial hyperplasia and other uterine causes, as well as some congenital uterine malformations, including female infertility caused by fallopian tube adhesions and fallopian tube obstruction. The disease is the primary factor. In the past, X-ray tubal iodine angiography for the diagnosis of fallopian tube obstruction is a traditional evaluation method. It is clinically recognized for its reproducibility and high accuracy. However, iodine allergy, false positive rate, and ray effects are factors. Limit its clinical application. In addition, laparoscopic tubal fluid and diagnostic curettage are intuitive and reliable, but they are traumatic to the patient and cannot be applied repeatedly.
The emergence of the world's full-featured, obstetrics and gynecology-based whole body machine, the high-end four-dimensional color Doppler ultrasound diagnostic instrument, provides doctors with valuable image data, and is a good news for female infertility patients. In the five fields of reproductive medicine, prenatal diagnosis, fetal heart, labor test and pelvic floor ultrasound, its excellent image quality and diagnostic software have played a huge diagnostic role.
More user-friendly ultrasound imaging
Four-dimensional uterine fallopian tube contrast-enhanced ultrasonography is the latest ultrasound imaging technique. It injects contrast agent into the uterine cavity to dilate the originally closed uterine cavity and fallopian tube, and then performs four-dimensional (dynamic three-dimensional) imaging, which is mainly real-time dynamic and more accurate display. The structure, shape and obstruction of the fallopian tube obtain a stereoscopic contrast image, which is objective and objective, and is conducive to the observation and judgment of the clinician.
The advantages of contrast-enhanced ultrasound are self-evident. First of all, the contrast agent rarely suffers from allergies; secondly, the contrast agent is non-toxic, side effects, especially for the liver and kidney; thirdly, no radiation is generated during the examination; fourth, the month after the angiography can be pregnant. Because of its dynamic nature, it is more convenient for doctors to conduct a comprehensive analysis and evaluation of the reproductive system, and has obvious advantages in the diagnosis and identification of uterine uterine lesions and tubal patency. To a certain extent, four-dimensional uterine fallopian tube contrast-enhanced ultrasound can replace uterine fallopian tube iodine angiography, and even laparoscopic examination, thereby reducing unnecessary clinical intervention and better meeting clinical needs. From the patient's point of view, the technique is not only easy to accept, but also can bury the fallopian tube to a certain extent while angiographic imaging, increasing the chance of pregnancy.
Although the four-dimensional hysterosalpingography has not been popularized in China for a long time, its advantages will undoubtedly make it the most important clinical value and broad application prospect in the field of gynecology.
Quiz
What preparations should be made before receiving 4D uterine fallopian tube ultrasound? What should you pay attention to after angiography?
It is only necessary to follow the ultrasound examination before the examination, no special preparation is required. Check the selection 3-7 days after the menstrual clean, check the leucorrhea cleanliness level 1-2.
Need to pay attention to the following points after inspection:
1. Can not be in the same room, take a bath or swim in two weeks;
2. Oral anti-inflammatory drugs;
3. A small amount of bloody secretions within a few days is normal.
