摘要

To provide image contrast enhancement method and MRI apparatus which can be also be used SPEC-IR pulse as an RF pre-pulse, while reducing the imaging time, and to obtain an image that emphasizes the contrast between different tissues, first the subject and comprising a second tissue having a tissue having a first resonant frequency, the resonant frequency of the second negative longitudinal magnetization of the first organization has a resonant frequency of the first By using a pulse sequence formed by and a measurement sequence section for measuring the echo signal before the RF pre-section having a RF pre-pulse for exciting the longitudinal magnetization excited by the RF pre-pulse is restored above zero, the image of the subject of measuring the echo signal from the subject, was reconstituted with the echo signal, on the basis of the phase information of the images, highlighting contrast enhancement for the other organization tissue either to get the contrast-enhanced image by applying the process.
