During the initial years, the use of MR imaging focused on the display of normal and abnormal cardiac anatomy. ECG-gated spin-echo imaging provides high-quality static images that clearly depict cardiac anatomy and a variety of anatomic abnormalities. However, it is now becoming clear that, with the addition of recent innovations, MR also is capable of evaluating cardiovascular physiology. With the use of fast imaging techniques, we can acquire images with essentially high temporal resolution so that cardiac function can be quantitated. Moreover, the use of proton and 31P MR spectroscopy provides additional information, which should enable the sequential monitoring of both cardiac function and metabolism.
在最初几年,磁共振成像(MR)的应用主要集中在显示正常和异常的心脏解剖结构。心电图门控自旋回波成像可提供高质量的静态图像,清晰描绘心脏解剖结构及各种解剖学异常。然而,现在越来越清楚的是,随着近期创新技术的加入,MR也能够评估心血管生理功能。通过使用快速成像技术,我们能够获取具有基本高时间分辨率的图像,从而可以对心脏功能进行定量分析。此外,质子和31P磁共振波谱学的应用提供了额外信息,这应能实现对心脏功能和代谢的连续监测。
