ABSTRACT:
A method and apparatus for NMR imaging a selected elongated region of a body wherein different portions of the elongated region respectively defined by the intersection of a number of discrete first slices perpendicular to the region with a second slice containing the whole region are imaged in turn. Each portion is imaged by exciting spins in one of the first slices (B1 (90), G1z, -G1z) and then rotating through 180.degree. any spins in the second slice (B2 (90), B3 (90), -Gy, Gy) the resulting spin echo of spins in the region of intersection of the first and second slices being then suitably encoded (Gx, G2z) and detected. The method and apparatus find particular application for imaging and spine of a patient.
