概括

在慢性肝病患者中,磁共振弹性图和T1/T2放松时间进行了比较. 肝脏T1映射显示了作为患者随访的非侵入性替代方案的希望.

科学领域:

医疗成像医学成像
放射学放射学是一门学科.
肝病学肝病学是一种肝病学.

背景情况:

慢性肝病 (CLD) 的诊断和监测通常依赖于侵入性手术.
非侵入性成像技术对于评估肝纤维化和肝硬度至关重要.
磁共振弹性成像 (MRE) 是测量组织硬度的一种成熟方法.

研究的目的:

为了比较使用MRE的肝脏和脏硬度测量与CLD患者的T1和T2放松时间.
评估T1和T2映射作为CLD的非侵入性生物标志物的潜力.

主要方法:

七十五名CLD患者和25名健康志愿者接受了MRI,不包括那些脂肪或铁积累很大的人.
用学生的t测试和皮尔森的相关性测试来比较MRE和T1/T2值.
评估了成像参数的相关性和诊断性能 (AUC).

主要成果:

肝脏MRE与肝脏T1 (r=0.51) 和T2 (r=0.30) 映射正相关.
脏MRE与脏T2相关 (r=0.37),但没有脏T1映射.
肝脏MRE (2.6kPa),T1 (619毫秒) 和T2 (52.5毫秒) 的切断值以高精度将患者与对照区分开来 (AUC 0.97,0.90,0.62).

结论:

非侵入性放松方法 (T1/T2映射) 可以在没有额外的设备的情况下进行.
肝脏T1映射可以作为MRE可行的替代方案,用于监测CLD患者.
在这种情况下,脏T1映射不是可靠的指标.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
