摘要
磁共振波谱(magnetic resonance spectros- copy,MRS)技术是研究眼眶及脑部肿瘤物质和能量代谢的有效方法,它可有助于脑肿瘤和眼眶肿瘤的诊断和鉴别诊断,能提供组织学分级、术后复发、疗效评价等重要信息。本文叙述了1HMRS(proton magnetic resonance spectroscopy)的基本工作原理及化合物分析的意义,阐明了不同肿瘤各化合物不同含量所引起的1HMRS的变化,并介绍了1HMRS在眼及脑肿瘤方面的应用现状。
Magnetic Resonance Spectroscopy (MRS) is a powerful method for the study of composition and energetic metabolism of orbital and brain tumor. It is very helpful for the diagnosis and differentiation of orbital and brain tumor with the information about histologic grading, postoperative recurrence and therapeutic evaluation. This article reviews basic work principle of 1HMRS(proton Magnetic Resonance Spectroscopy)and significance of compound analysis; it clarifies change in 1HMRS caused by the aniso-content of compound in different kinds of tumor; it recommends the clinical application of 1HMRS in orbital and brain tumor as well.·
