    Abstract: The present disclosure discloses a chemical shift coded imaging method based on a transition region and regional iterative phasor extraction. Acquiring an initial image, and determining an initial phasor solution of the transition region based on the initial image; performing regional iterative phasor extraction in at least two set directions by taking the initial phasor solution as initial information, and obtaining a target phasor solution based on a regional iterative phasor extraction result corresponding to each set direction; and determining a first chemical composition signal and a second chemical composition signal based on the target phasor solution, and performing chemical shift coded imaging based on the first chemical composition signal and/or the second chemical composition signal. By means of regional iterative phasor extraction in a plurality of dimensions, wrong phasor information is transferred independently along different dimensions, wrong information transferred in different directions is excluded.

    Abstract: An Alzheimer's disease biomarker, and a screening method therefor and use thereof. The Alzheimer's disease biomarker is 11(Z), 14(Z)-eicosadienoic acid. The screening method for the Alzheimer's disease biomarker comprises: acquiring samples, testing the samples, and performing structural identification and data analysis on metabolites in the samples, wherein specifically, metabolites in faeces samples can be tested by liquid chromatography-mass spectrometry, to carry out structural identification on the metabolites; and selecting a metabolite showing a difference from the metabolite level of a control group as the Alzheimer's disease biomarker. Using 11(Z), 14(Z)-eicosadienoic acid as an Alzheimer's disease biomarker is of great significance to clinical early diagnosis of Alzheimer's disease; the present invention can be used for preparing a diagnostic tool for Alzheimer's disease, predicting the individual treatment effects of patients with Alzheimer's disease, and preparing drugs for treating Alzheimer's disease.
