Title:
MAGNETIC RESONANCE IMAGING METHOD, MAGNETIC RESONANCE IMAGING APPARATUS, MAGNETIC RESONANCE IMAGING PROGRAM, AND DESIGN DEVICE
Document Type and Number:
Japanese Patent JP2011177504
Kind Code:
A
Abstract:

To provide a B1-robust and T1-robust nuclide suppression technique.

An MRI pulse sequence includes a spectrally-selective refocusing pulse (hereafter, REFUSAL (REFocusing Used to Selectively Attenuate Lipids) pulse). The REFUSAL pulse selectively refocuses water spins and avoids refocusing lipid spins. The REFUSAL pulse ideally maximizes refocusing for water and minimizes any lipid refocusing. Only those spins that were refocused with the spectrally selective REFUSAL pulse continue to evolve coherently and generate a train of echoes. Those spins that were minimally refocused are spoiled and thus do not contribute signal to the final image.
