FIG 1. EPID versus LSDI in a healthy volunteer.
A and B, EPID (2000/90/1; b = 600 s/mm2) trace images at two anatomic levels show geometric distortion of the brain stem and artifactual high signal intensity in the temporal lobes and anterior frontal lobes.
C and D, LSDI (2736/89/1; b = 600 s/mm2) trace images at corresponding levels show less geometric distortion and less magnetic-susceptibility artifact.
