What does a B-ultrasound check?
B-ultrasound (ultrasound examination) is a non-invasive and painless medical imaging technology that is widely used in clinical diagnosis. It helps doctors observe the structure and function of the human body's internal organs through high-frequency sound wave reflection imaging. The following is a summary of common application scenarios, precautions, and recent hot topics for B-ultrasound examination.
1. Common uses of B-ultrasound examination
| Check site | Main purpose | Applicable people |
|---|---|---|
| abdomen | Check for lesions (such as stones and tumors) in the liver, gallbladder, pancreas, spleen, kidney and other organs | Patients with abdominal pain and jaundice |
| Gynecology | Observe the structure of the uterus and ovaries, and diagnose pregnancy, fibroids or cysts | Pregnant women and infertility patients |
| Heart (echocardiogram) | Assess heart size, valve function and blood flow | cardiovascular disease patients |
| thyroid | Detect nodules, inflammation or tumors | Patients with neck swelling and hyperthyroidism |
| Blood vessel | Diagnose varicose veins, blood clots or arteriosclerosis | Patients with lower limb swelling and hypertension |
2. Precautions for B-ultrasound examination
1.fasting requirement: Abdominal B-ultrasound requires fasting for 8 hours to avoid interference from intestinal gas.
2.Prepare to hold in your urine: Before gynecological or prostate examination, you need to drink water to hold in your urine to fill your bladder.
3.Dress loosely: It is recommended to wear easy-to-remove clothing and avoid metal jewelry.
4.No radiation risk: Pregnant women can use it safely, but no check-up is necessary in the early stages of pregnancy.
3. Recent hot topics and B-ultrasound related progress
1.AI-assisted ultrasound diagnosis: In the past 10 days, many hospitals have introduced artificial intelligence technology to improve the accuracy of thyroid nodule identification to more than 90%.
2.Portable B-ultrasound equipment: A brand’s newly launched handheld ultrasound machine has reached the top of the technology hot search, and is suitable for first aid in remote areas.
3.Controversial topics: Internet celebrities' promotion of "fetal gender B-ultrasound" services triggered ethical discussions, and the National Health Commission reiterated that non-medical identification is prohibited.
4. Comparison between B-ultrasound and other imaging examinations
| Check type | Advantages | limitation |
|---|---|---|
| B-ultrasound | Real-time dynamics, no radiation, low price | Lower resolution due to gas/bone interference |
| CT | 3D imaging, suitable for emergencies | There is radiation and the cost is higher |
| MRI | Best soft tissue contrast | The examination takes a long time and has many contraindications |
Conclusion
As a basic screening tool, B-ultrasound plays an irreplaceable role in disease diagnosis and health management. As technology advances, its application scenarios are still expanding. It is recommended to choose the appropriate examination method according to the guidance of the doctor and avoid blindly pursuing high-end imaging examinations.
