Abstract:
Phosphorus compounds exist in the tissue of human body,providing important information about microenvironment changes of diseases. Phosphorus magnetic resonance spectroscopy (31P-MRS) is a non-invasive method to observe energy metabolism and biochemical changes of human tissue, which can be utilized in diagnosing disease and monitoring response to therapy. However, the magnetogyric ratio of phosphorus is low, and the in vivo content is relatively low, resulting low signal-to-noise ratio of phosphorus spectrum. It is very important to choose suitable scanning sequence to improve the quality. The characteristics, advantages and disadvantages of sequences used in 31P-MRS were reviewed this article.
