Rapid 3D-FSE sequences allow for isometric acquisition of images that can be reformatted in multiple planes without slice gaps, enabling acquistion of an full diagnostic knee MR dataset in 6 minutes. These methods typically require a trade-off between signal-to-noise ratio and image blur. We present a 3D-FSE sequence with improved SNR and decreased blur for diagnosis of pathologies of the knee. Improvements in phantom, volunteer, and patient images are presented.
