Abstract
Systems and methods are provided for producing diffusion-weighted images of a subject using a magnetic resonance imaging (MRI) system. The method includes performing a stimulated echo preparation module using non-selective radio-frequency (RF) pulses designed to induce a stimulated echo, performing an acquisition module that includes a multi-slice acquisition of MR data in the presence of diffusion gradients, and reconstructing the diffusion-weighted images of the subject from the MR data.
Claims24
A method for producing diffusion-weighted images of a subject using a magnetic resonance imaging (MRI) system, the method comprising:
- performing a stimulated echo preparation module using non-slice-selective radio-frequency (RF) pulses designed to induce a stimulated echo;
- performing an acquisition module that includes a multi-slice acquisition of MR data in the presence of diffusion gradients;
- and
- reconstructing the diffusion-weighted images of the subject from the MR data.
A magnetic resonance imaging (MRI) system comprising:
- a magnet system configured to generate a static magnetic field (B0) about at least a portion of a subject arranged in the MRI system;
- a plurality of gradient coils configured to apply magnetic gradients to the static magnetic field;
- a radio frequency (RF) system configured to apply an excitation field to the subject and acquire MR image data from the subject;
- a computer system programmed to:
- control the gradient coils and the RF system to:
- perform a stimulated echo preparation module using non-selective radio-frequency (RF) pulses designed to induce a stimulated echo;
- perform an acquisition module that includes a multi-slice acquisition of MR data in the presence of diffusion gradients;
- and
- reconstruct the diffusion-weighted images of the subject from the MR data.
