Three‐dimensional (3D) magnetic resonance imaging allows thin‐section acquisition and therefore more accurate multiplanar reconstruction than conventional two‐dimensional spin‐echo imaging. Unfortunately, addition of a third acquisition plane extends imaging time greatly. With gradient‐echo techniques, 3D acquisitions have become clinically useful. These techniques are limited, however, by susceptibility and other field inhomogeneity artifacts and decreased signal‐to‐noise ratios compared with spin‐echo techniques. The authors describe implementation of a true spin‐echo 3D technique that, by using fast spin‐echo parameters, reduces acquisition time to a clinically useful level. Potential applications of the technique are demonstrated.
