Abstract

See full text

A method for measuring pH includes using amide protons as an endogenous contrast agent, measuring a chemical exchange saturation transfer effect ratio R of amide protons corresponding to a pH-known amide proton solution under different saturation powers, then establishing a function relation between pH and R according to different pH-known amide proton solutions and the corresponding measured R thereto, and finally calculating the desired pH according to experimentally measured Ri and the function relation. The method can eliminate the impact of concentration and does not require any estimation or measurement of the parameters such as the concentration of exchangeable protons, the longitudinal relaxation time of water, etc., and therefore can measure pH more accurately, conveniently and non-invasively.
