概括

三维对比增强超声波 (3D-CEUS) 准确评估微波剥离 (MWA) 区域,显示与CECT有很强的一致性. 临床数据,而不是ex vivo模型,应该优化MWA规划.

科学领域:

医疗成像医学成像
干预性放射学干预性放射学
在瘤学瘤学.

背景情况:

微波除 (MWA) 是肝脏瘤的关键治疗方法.
准确评估MWA区域尺寸对于治疗疗效和规划至关重要.
在评估废除区域时,成像方法和动物模型之间存在差异.

研究的目的:

为了比较三维对比增强超声波 (3D-CEUS) 与对比增强计算机断层扫描 (CECT) 来评估MWA区域的大小和形状.
量化人类MWA区域和ex vivo牛肝模型之间的差异.
为了优化手术前的规划,用于热除手术.

主要方法:

对33名接受肝脏瘤皮MWA治疗的患者的回顾性分析.
对于MWA区域参数 (LAD,DS,体积,RI) 的3D-CEUS和CECT的相关性和一致性分析.
临床病例和ex vivo牛肝模型之间的切除区域特征的比较.

主要成果:

在MWA区域评估中,3D-CEUS和CECT之间存在强烈的相关性 (Pearson/Spearman r > 0.87) 和良好的一致性 (ICC 0.81-0.95).
在ex vivo牛肝模型中,除了临床病例外,还显示了显著更大的切除区域 (LAD,DS,RI).
两种成像方法都证实了临床和活体数据之间的这些差异.

结论:

3D-CEUS对于评估MWA区域形态和尺寸的高度准确.
临床3D-CEUS数据,而不是外体模型,对于改善手术前规划系统至关重要.

Ultrasonography

Ultrasonography

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.
During an ultrasonography procedure, a handheld device called...
