Title:
水/脂肪分離を用いた位相感応型反転回復MRI
Document Type and Number:
Japanese Patent JP6581584
Kind Code:
B2
Abstract:
A phase sensitive inversion recovery (PSIR)-based MR imaging method of at least two chemical species having different MR spectra enables distinction between myocardial scar and myocardial triglyceride deposition. The method includes the steps of: a) generating echo signals at two or more different echo times by subjecting an object (10) positioned in the examination volume of a MR device (1) to an imaging sequence of RF pulses and switched magnetic field gradients, which imaging sequence is an inversion recovery sequence including an inversion RF pulse followed by an excitation RF pulse after an inversion recovery time; b) acquiring the echo signals; c) separating signal contributions of the at least two chemical species to the acquired echo signals; and d) reconstructing a phase-sensitive MR image (28, 29) from the signal contributions of at least one of the chemical species.
