概括
无线Vscan Air超声波设备可用于未明确的病变的超声波导向活检,但在超过3厘米的深度下,图像质量显著下降. 虽然它适合没有经验的用户,但它并不能完全取代深层病变活检中的高端系统.
科学领域:
- 医疗成像医学成像
- 干预性放射学 干预性放射学
- 超声波技术 超声波技术 超声波技术
背景情况:
- 超声导向活检对于诊断微循环变化的不明确病变至关重要.
- 通常需要高端超声波设备,这带来了技术挑战.
- 像Vscan Air这样的无线手持超声波设备为简化干预提供了潜力.
研究的目的:
- 评估Vscan Air无线超声波设备用于干预活检.
- 与高端系统相比,评估其图像质量和可用性.
- 为了确定其适用于不明确病变的活检.
主要方法:
- 使用了体外肝脏模型,模拟了不同深度 (1-5厘米) 的病变.
- 一个高级培训课程的参与者使用问卷评估图像质量.
- 在干预之前,干预期间和干预后评估图像质量,以高端设备为参考.
主要成果:
- 11名参与者评估了深达5厘米的病变.
- 对于所有目标病变,充分的活检都取得了成功.
- 与高端设备相比,Vscan Air的图像质量从3厘米深度显著下降 (p <0.01).
- 尽管质量下降,但缺乏经验的用户可以通过手持设备充分评估病变.
结论:
- 移动干预超声波,如Vscan Air,是不清楚瘤病变的活检的可行选择.
- 它的有效性受到深度的限制,特别是对于超过3厘米的病变.
- 它为局部深度有限的干预提供了潜在的替代方案.

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...
