What can uterine B-ultrasound detect?
Uterine B-ultrasound (ultrasound) is a common non-invasive examination method in gynecology. It uses high-frequency sound wave imaging technology to observe the structure and lesions of the uterus, ovaries and other reproductive organs. The following is a compilation of hot topics about uterine B-ultrasound examination that have been hotly discussed on the Internet in the past 10 days. We will provide you with a detailed analysis of the examination scope and precautions based on medical knowledge.
1. Scope of uterine B-ultrasound examination
Uterine B-ultrasound can clearly display the uterine shape, endometrial thickness, ovarian structure, etc. The following are its common examination contents:
| Check items | Specific content | clinical significance |
|---|---|---|
| Uterine size and shape | Measure the length, width and thickness of the uterus | Diagnose developmental abnormalities (such as infantile uterus) or fibroids |
| endometrium | Observe intimal thickness and echo uniformity | Diagnose polyps, growths or cancer |
| Uterine fibroids | Locate the number, size and blood flow signals of fibroids | Assess the need for surgical intervention |
| ovarian cyst | Differentiate between physiological cysts and pathological tumors | Monitoring for chocolate cysts or polycystic ovaries |
| Pregnancy related | Confirm the location of the gestational sac and embryo development | Screening for risk of ectopic pregnancy or miscarriage |
2. Recent hot topics: B-ultrasound new technologies and controversies
1.3D ultrasound applications: Recently, social platforms have been hotly discussing that three-dimensional B-ultrasound can present uterine malformations (such as septate uterus) three-dimensionally and improve diagnostic accuracy.
2.Endometrial cancer screening controversy: Some popular science bloggers pointed out that B-ultrasound alone cannot diagnose endometrial cancer and needs to be combined with pathological biopsy, causing netizens to pay attention to the limitations of the examination.
3."B-ultrasound radiation" rumors: In response to the concerns of some pregnant women, medical experts have once again clarified that ultrasound examinations do not contain ionizing radiation and are safe to use during pregnancy.
3. Inspection Precautions (Structured Suggestions)
| Check type | Prepare requirements | best time |
|---|---|---|
| Transabdominal B-ultrasound | Need to hold in urine to keep bladder full | 3-7 days after menstruation is clean |
| Transvaginal B-ultrasound | Empty your bladder and avoid your period | Ovulation monitoring (people preparing for pregnancy) |
4. Frequent questions and answers from netizens
1.“Can B-ultrasound detect cervical cancer?”: Conventional B-ultrasound has a low detection rate of early cervical cancer and needs to be combined with TCT and HPV testing.
2."What should I do if I find a thick intima during examination?": It needs to be judged based on the menstrual cycle. Postmenopausal women with endometrium > 4mm need further examination.
3."Which is better, B-ultrasound or vaginal ultrasound?": Vaginal super-resolution is higher, but it is not suitable for virgins or those with acute vaginal inflammation.
5. Summary
As a basic gynecological examination, uterine B-ultrasound can effectively screen most organic lesions, but its limitations should be noted. Recently, the public has become more concerned about the advancement of examination technology (such as contrast-enhanced ultrasound), and it is recommended to choose the appropriate examination plan based on the doctor's advice. Regular B-ultrasound examination (especially for women over 35 years old) is of great significance for early detection of uterine fibroids and endometrial lesions.
