For fast volumetric spinal cord imaging, a 3D acquisition strategy for the recently published Averaged Magnetization Inversion Recovery Acquisitions (AMIRA) approach was developed: AMIRA-3D. It typically acquires 12 slices with a resolution of 0.67 x 0.67 x 3.0 mm3 in 5:27 min, which represents an acquisition time of just 27 secs per slice. As common to all AMIRA approaches, images with remarkable different tissue contrast are acquired for each slice (or partition) simultaneously. Some of these images can be combined to both enhance and fine-tune the desired tissue contrast.
