Systems and methods for magnetic resonance imaging

A method for magnetic resonance imaging (MRI), comprising:

• obtaining a plurality of echo signals relating to a subject, the plurality of echo signals being excited by an MRI pulse sequence applied to the subject;
• and
• simultaneously performing a first measurement and a second measurement on the subject based on the plurality of echo signals, the first measurement including at least one of a relaxation parameter measurement or a myelin water fraction (MWF) measurement, the second measurement including at least one of an amide proton transfer (APT) measurement or a pH measurement;
• and
• sending a quantitative measurement result of the first measurement and the second measurement to a terminal for display, wherein the MRI pulse sequence comprises:
• a chemical exchange and saturation transfer (CEST) module configured to selectively excite exchangeable protons or exchangeable molecules in the subject;
• and
• a gradient and spin echo (GRASE) pulse sequence configured to excite a plurality of gradient echoes and a plurality of spin echoes.

A non-transitory computer readable medium, comprising at least one set of instructions for magnetic resonance imaging (MRI), wherein when executed by at least one processor, the at least one set of instructions directs the at least one processor to perform a method, the method comprising:

• obtaining a plurality of echo signals relating to a subject, the plurality of echo signals being excited by an MRI pulse sequence applied to the subject;
• and
• simultaneously performing a first measurement and a second measurement on the subject based on the plurality of echo signals, the first measurement including at least one of a relaxation parameter measurement or a myelin water fraction (MWF) measurement, the second measurement including at least one of an amide proton transfer (APT) measurement or a pH measurement;
• and
• sending a quantitative measurement result of the first measurement and the second measurement to a terminal for display, wherein the MRI pulse sequence comprises:
• a chemical exchange and saturation transfer (CEST) module configured to selectively excite exchangeable protons or exchangeable molecules in the subject;
• and
• a gradient and spin echo (GRASE) pulse sequence configured to excite a plurality of gradient echoes and a plurality of spin echoes.
