What is the principle of IVF imaging

IVF is a medical examination method, which is used to observe the internal conditions of female reproductive system through X-ray technology and appropriate contrast injection to help diagnose infertility. The principle of IVF imaging mainly includes: examination preparation, contrast injection X-ray imaging and interpretation of results. The principle of IVF imaging will be described in detail from these aspects.

1、 Inspection preparation

Before IVF, the doctor will make necessary preparations for the patient. First, the doctor will understand the patient's medical history and symptoms, and conduct a comprehensive physical examination. Secondly, patients need vaginal cleaning to reduce the risk of infection. In addition, the patient also needs to fast within 2 hours before the examination and empty the bladder.

2、 Contrast injection

When performing IVF imaging, the doctor will inject a special contrast agent into the patient's uterine cavity. This contrast medium is generally sterile and low toxic, and can produce corresponding images under X-ray for doctors to observe. The injection of contrast media is generally divided into two ways: hysterography and iliac arteriography. Hysterography is to inject contrast agent into uterine cavity, and then observe the shape of uterine cavity and the patency of fallopian tube. Iliac arteriography is to insert a catheter into the iliac artery through vagina or rectum to deliver contrast to the uterus to observe the condition of the uterus and fallopian tubes.

III X-ray imaging

After contrast injection, the patient will be sent to the X-ray room for imaging. X-ray technology can penetrate human tissues to form images, and through digital processing, doctors can more clearly observe the condition of the patient's uterus, fallopian tubes and nearby organs. During X-ray imaging, the patient needs to keep calm and make corresponding postures according to the doctor's instructions. Doctors will acquire multiple images from different angles through the X-ray machine, and observe and record the changes of relevant structures in a timely manner.

4、 Interpretation of results

After X-ray imaging, the doctor will observe and analyze the patient's imaging results. If the contrast agent can pass through the fallopian tube and reach the abdominal cavity smoothly, it indicates that the patient's fallopian tube is unobstructed, which is helpful to eliminate problems such as ectopic pregnancy in the fallopian tube. At the same time, doctors will also observe the shape of the uterus, whether the fallopian tube is complete and other factors. In general, IVF is a medical examination method to observe the internal conditions of female reproductive system through X-ray technology and contrast injection. Through inspection preparation, contrast injection Steps such as X-ray imaging and result interpretation can help doctors understand patients' infertility problems and provide important reference for subsequent diagnosis and treatment. Therefore, IVF imaging plays an important role in the diagnosis of infertility.
