Endometrial cancer is a common gynecological malignancy. Early diagnosis is of great significance for treatment and prognosis. The ultrasound scanner is a non-invasive test method that can be used to assess characteristics such as thickness, morphology and structure of the endometrium, as well as to detect abnormal benign and malignant changes. Ultrasound scanners play a crucial role in the early screening and diagnosis of endometrial cancer.

First, basic principles

Ultrasonic scanners use ultrasonic technology to image human tissue. When ultrasonic waves pass through human tissue, they are reflected back by resistance of different densities within the tissue. Ultrasound scanners collect these reflected signals and turn them into images that give information about the morphology and structure of the tissue.

2. Application value

Early diagnosis

In the early stages of endometrial cancer, the lesions are usually small, and ultrasound scanners can help doctors find them early. Ultrasound scanners can quickly and accurately measure the thickness and shape of the endometrium, allowing early detection of signs of cancer when abnormal changes occur in the endometrium.

Evaluation of therapeutic effect

Ultrasound scanners can also be used to assess the effectiveness of treatments. During treatment, doctors need to know the size and location of the tumor so that they can adjust the treatment plan. Ultrasound scanners can help doctors accurately observe changes in the tumor and assess the effects of treatment.

Guided operation

For patients who need surgery, ultrasound scanners can aid surgery, guide doctors to the exact location of the tumor, and guide the scope of surgical excision to avoid misincision or missing incision.

3. Application process

Patient preparation

Patients need to go to hospital on an empty stomach and have their bladder and rectum emptied so that doctors can better view the uterus and surrounding tissues.

Check operation

The doctor inserts a special probe into the patient's vagina and uses an ultrasound scanner to examine it. The probe is moved in the direction of the endometrium to get a full view of the endometrium.

Result analysis

The doctor will analyze the patient's condition based on the results of the test and conduct further tests or treatment if necessary.

4. Technological advantages

non-invasive

The ultrasound scanner is a non-invasive procedure that does not require procedures such as puncture or contrast injection and does not harm the patient.

High accuracy

The ultrasound scanner can clearly show the thickness and shape of the endometrium, which can accurately determine the location and size of the cancer.

Simple operation

Ultrasound scanners are simple to operate and do not require complex instruments and equipment. The doctor simply inserts the probe into the patient's vagina to perform the examination.

Good repeatability

The ultrasonic scanner can inspect the same part many times, and its results are highly repeatable, which can improve the accuracy and reliability of diagnosis.

V. Conclusion

Ultrasound scanners are widely used in the diagnosis of endometrial cancer. Its advantages are non-invasive, high accuracy, simple operation and good repeatability, making it an ideal tool for early diagnosis and evaluation of therapeutic effects. At the same time, with the continuous progress and development of technology, ultrasonic scanner will be more and more mature and perfect, to provide clinicians with more accurate, rapid, convenient diagnosis methods.
