胆囊息肉超声评估
用于检测和特征描述胆囊息肉并将其与胆结石区分的专门超声。
什么是 Ultrasound Gallbladder Polyp?
胆囊息肉超声是专注于胆囊的专门腹部超声检查。它检测息肉样病变,测量其大小,并帮助区分真性息肉与假性息肉(如嵌顿在胆囊壁内的结石)。
工作原理: 使用高频换能器,声波创建胆囊的详细图像。息肉表现为从胆囊壁向腔内突出的回声(明亮)结构。与结石不同,息肉不产生声影且不随患者体位改变而移动。
Ultrasound Gallbladder Polyp 的常见用途
偶发性息肉检测
Identify polyps found during imaging for other reasons
息肉大小测量与监测
Track polyp growth over time to determine need for intervention
恶性肿瘤风险评估
Identify features suggesting gallbladder cancer (size >1 cm, rapid growth, vascularity)
手术规划
Help determine need for cholecystectomy based on polyp characteristics
症状性胆囊评估
Assess gallbladder in patients with right upper quadrant pain
胆囊切除术后监测
Evaluate cystic duct remnant or unusual findings after gallbladder removal
优势
- ✓无辐射暴露
- ✓实时成像允许评估移动性
- ✓检测甚至小息肉效果优异
- ✓可区分息肉与结石
- ✓广泛可用且相对便宜
局限性
- ⚠操作者依赖
- ⚠在高体脂或肠道气体过多的患者中受限
- ⚠在某些患者中可能难以显示胆囊
- ⚠不能明确确定组织学(良性 vs. 恶性)
- ⚠可能遗漏颈部或底部的息肉
- ⚠对小息肉的准确性低于内镜超声

相关影像方式
CT or MRI may be used for further characterization, especially if malignancy is suspected. Endoscopic ultrasound (EUS) provides superior detail for small polyps and can obtain tissue samples.
CT
CT scans use X-rays to create detailed cross-sectional images of the body. They are particularly useful for detecting bone fractures, tumors, and internal bleeding.
MRI
MRI uses powerful magnets and radio waves to produce detailed images of organs and soft tissues. Excellent for brain, spine, and joint imaging.
