概括

三种光学连贯性断层扫描 (OCT) 装置在测量视网膜 (RT) 和胸膜厚度 (ChT) 中表现出极好的重复性和可重复性. 然而,发现了重要的设备间协议问题,影响了临床一致性.

科学领域:

眼科医生眼科眼科
生物医学工程生物医学工程
医疗成像医学成像

背景情况:

光学连贯断层扫描 (OCT) 对于评估视网膜和胸膜厚度 (RT和ChT) 是至关重要的.
评估不同OCT设备的一致性对于可靠的临床数据和研究至关重要.
在OCT设备之间的变化可能会影响诊断准确性和治疗监测.

研究的目的:

评估三种用于测量RT和ChT的OCT设备 (VG200I,Triton,RTVue) 的可重复性,可复制性和一致性.
为了比较使用内置软件获得的测量结果与用于冠状腺厚度 (ChT) 的自定义算法.
为了确定在不同OCT平台的厚度测量中可能存在的差异.

主要方法:

用VG200I,Triton和RTVue OCT设备分析了68只眼睛.
可重复性由一个操作员进行两个检查来评估;可重复性由第二个操作员进行.
测量包括平均RT/ChT (VG200I,Triton) 和底RT/ChT (SFRT,SFChT) (RTVue),并比较了ChT的自动化和定制算法.

主要成果:

这三种OCT设备都表现出高的重复性和可重复性,其类内相关系数 (ICC) 通常高于0.760.
在SFRT,SFChT和整体RT/ChT测量中观察到显著的设备间差异.
虽然机器之间的相关性很高 (ρ > 0.655),但平均差异表明设备之间的一致性很差.

结论:

经过评估的OCT设备在RT和CHT测量方面表现出强大的重复性和可重复性.
尽管单个器件一致性很高,但在三个OCT器件之间发现一致性很差.
临床使用需要仔细考虑特定于设备的测量和潜在的设备间变异性.

Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
