评估CTTH和MRI序列 (FLAIR,DWI) 之间的关系.
探索T2/FLAIR不匹配和扩散限制在儿科CTTH中的诊断价值.

主要方法:

对3462个儿童大脑MRI扫描的回顾性分析.
鉴定了104名双边CTTH患者.
对DWI,FLAIR和T2/FLAIR不匹配和扩散限制的后续扫描进行视觉评估.

主要成果:

患有CTTH的儿科患者中,有60.4%的儿科患者表现出T2/FLAIR不匹配.
在40.8%的患者中观察到扩散限制.
在T2/FLAIR不匹配和临床诊断 (p=.020) 之间,以及在扩散限制和T2/FLAIR不匹配 (p=.017) 之间发现了显著的相关性.

结论:

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...
