| 摘要 |
Systems and methods employing spin editing techniques to improve magnetic resonance spectroscopy (MRS) and magnetic resonance spectroscopic imaging (MRSI) are discussed. Using these spin editing techniques, magnetic resonance signals of one or more unwanted chemicals (that is, chemicals whose signals are to be filtered out or suppressed) chemicals can be suppressed, so that the signal(s) of a first set of chemicals can be obtained without signals from the one or more unwanted chemicals. Information about and differences between the molecular topologies of the first set of chemicals and the one or more unwanted chemicals can be used to design a sequence that suppresses the one or more unwanted chemicals while allowing acquisition of signal(s) from the first set of chemicals. |
