概括

准确的肝体积测量对于活体供体肝移植至关重要. 自动化CT工具显示可靠的结果,Synapse对特定的肝脏部分显示出卓越的准确性,有助于手术规划.

科学领域:

放射学
手术规划
医学成像分析

背景情况:

准确的手术前肝体积测量对于成功的活体供体肝移植 (LDLT) 是至关重要的.
手动CT体积测量需要大量的时间和操作人员.
已开发出自动化和半自动化CT体积测量方法以提高效率和准确性.

研究的目的:

为了比较一个半自动 (Vitrea) 和两个自动 (Synapse,UI) CT体积测量工作站的准确性.
评估右叶,左叶和左侧段肝移植体积的估计.
评估与手术中的移植重量相关的准确性.

主要方法:

对接受LDLT治疗的95名活体肝脏捐赠者的回顾性研究.
来自Vitrea,Synapse和UI工作站的估计移植体积与实际移植重量 (AGW) 的比较.
对相关性的评估,百分比误差,观察者间的共识,以及捐赠者的年龄/性别的影响.

主要成果:

这三种CT体积测量方法都与AGW有很强的相关性 (p < 0. 001).
与Vitrea和UI相比,Synapse的肝脏分析显示右叶和左侧段体积估计的准确性显著提高.
观察者之间有很高的一致性,而捐赠者的年龄或性别对准确性没有显著影响.

结论:

所有评估的CT体积测量工具 (Vitrea,Synapse,UI) 都可靠且易于使用,用于LDLT手术前规划.
Synapse的肝脏分析为右叶和左侧部门提供了最高的准确性.
这些发现表明Synapse在LDLT手术决策中的潜在优势.

Kidney Transplant I: Introduction

Kidney Transplant I: Introduction

A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
