- 放射学 放射学是一门学科.
- 医疗成像医学成像
- 胃肠病学 胃肠病学
背景情况:
- 患者经常禁食进行腹部超声波,但支持其益处的证据有限.
- 长时间的禁食会带来低血糖和营养不良等风险,特别是在某些患者群体中.
- 避免不必要的禁食对于患者的福祉至关重要.
研究的目的:
- 评估术前禁食对腹部超声波图像质量的影响.
- 为了比较不同超声波前饮食干预的图像质量.
- 为了确定禁食是否对于最佳的诊断成像至关重要.
主要方法:
- 这是一项前性,调查者盲目的研究,包括215名住院患者接受腹部超声波检查.
- 随机分为三组:长时间禁食,定期早餐或液体营养补充剂.

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
