概括

周心T1映射显示急性心周炎患者的较低值. 这种非对比心血管磁共振 (CMR) 技术有效地识别了急性心膜炎,与晚期加多增强严重程度相关.

科学领域:

心血管磁共振 (CMR) 图像成像
心脏成像生物标志物生物标志物
周心疾病诊断周心疾病诊断

背景情况:

诊断急性心膜炎往往依赖于临床标准和成像.
无对比心血管磁共振 (CMR) 技术对于患者的安全性和可访问性是可取的.
周心T1映射提供了对心肌和周心组织属性的定量评估.

研究的目的:

评估心周T1映射作为诊断急性心周炎的非对比支持参数.
调查心周T1值与急性心周炎的临床/生物标志物数据之间的关联.
为了比较患有急性心膜炎的患者和健康对照者之间的心周T1映射值.

主要方法:

对35名急性心膜炎患者和17名匹配的健康对照者的CMR扫描进行了回顾性分析.
测量心周T1映射值,包括输出和层厚度.
患者和对照组之间的心周T1值的比较,使用多变量和ROC曲线分析.

主要成果:

与对照组 (3268 ± 362 ms) 相比,急性心周炎患者表现出明显较低的心周T1映射值 (2137 ± 519 ms) (p=0.001).
周心T1映射值与周心晚期加多增强 (LGE) 的严重程度独立相关 (β = -3.271,p=0.003).
接收器操作特征分析表明,在分辨性急性心膜炎 (AUC=0.97) 中,心膜T1映射的诊断性能优异.

结论:

心周T1映射作为一种有价值的非对比CMR参数,用于识别急性心周炎.
该技术显示了与心周LGE的严重程度的独立关联.
非对比的心周T1映射可以提高急性心周炎的诊断能力.

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...
