First-pass cardiac perfusion MRI demands fast imaging
techniques to achieve high spatial resolution and
coverage within a small acquisition window. We recently
developed a CS method BLOSM to accelerate first-pass
perfusion with respiratory motions, and demonstrated the
advantages of BLOSM using retrospectively-undersampled
first-pass data. In the present study, we aimed to
evaluate prospectively-accelerated BLOSM first-pass
images in patients with suspected heart disease. Using
prospectively accelerated data, BLOSM showed improved
reconstruction quality compared to k-t SLR. BLOSM may
provide clinically acceptable image quality at higher
acceleration rates such as 6, even with the presence of
respiratory motion.
