Recent Advances on Magnetic Resonance Spectrum Imaging in Diagnosis and Differential Diagnosis of Pancreatic Cancer

目的总结磁共振波谱成像的原理及其在胰腺癌诊断及鉴别诊断的应用进展。方法收集并复习国内外最新相关文献。结果磁共振波谱成像是利用磁共振现象及化学位移现象来检测物质分子组成的一种技术,临床及科研中常用的波谱包括1H、31P和23Na的波谱分析。结论磁共振波谱成像作为目前唯一能够无创性定性定量提供活体内生化信息的方法,对胰腺癌诊断及鉴别诊断具有重要意义。

Objective To summary the principle of magnetic resonance spectroscopy imaging and its application progress in diagnosis and differential diagnosis of pancreatic cancer. Methods The newest related literatures of home and abroad were collected and reviewed. Results Magnetic resonance spectroscopy imaging was a technology using the magnetic resonance phenomena and chemical shift phenomena to measure molecular organization. The spectroscopy most commonly used in clinical and scientific research includes ^1H, ^31P, and ^23Na. Conclusion Magnetic resonance spectroscopy as the only approach to noninvasive quantitative provding biochemical information in vivo, has an important significance to the diagnosis and differential diagnosis of pancreatic cancer.
