Nuclear magnetic resonance (NMR) has become an important non-invasive investigative technique in medicine and biology. The most recent development has been the ability to perform magnetic resonance spectroscopy (MRS) in selected regions within the human body. Such volumes can be selected by techniques which fall into the following broad categories: surface coil methods, surface coils with depth selection, volume selection and chemical shift mapping. The latter two methods use magnetic field gradients, present on magnetic resonance imaging systems, to select the volume. MRS can be used to measure phosphorus and proton metabolites and hence study tissue biochemistry in-vivo.
核磁共振（NMR）已成为医学和生物学中一种重要的非侵入性检测技术。最新进展是能够在人体特定区域进行磁共振波谱分析（MRS）。此类体积可通过以下大致分类的技术来选择：表面线圈法、带深度选择的表面线圈法、体积选择法和化学位移成像法。后两种方法利用磁共振成像系统上存在的磁场梯度来选择体积。MRS可用于测量磷和质子代谢物，从而在体内研究组织生物化学。
