Ultrafast diffusion-sensitive MR imaging of brain on an open scanner at 0.2 T.
We describe new strategies for fast diffusion-sensitive MR imaging of ischemic brain or spinal cord lesions. The methods provide diagnostic image quality in less than 1 s per section and are used in conjunction with low-field-strength open MR scanners. Single-shot sequences combine diffusion-sensitive preparation with a modified fast spin-echo data acquisition. Results are presented from healthy volunteers and from two patients with recent and older ischemic brain lesions.
