Multiband Diffusion-Weighted Breast MRI
This novel technique reduces distortion in high-resolution diffusion MRI. Diffusion MRI is often limited by blurring or distortion, which is fundamentally proportional to the field of view (FOV) of the image. These effects can be overcome by exciting only a narrow "strip" of signal at each time. The narrow "strips" have reduced FOV and thus reduced distortion. In this work, we have developed a way to simultaneously excite multiple strips, and use multiple coils to separate the signals from the strips. This enables high-resolution images with reduced distortion over the entire FOV of the subject.
