T1-weighted gradient-echo axial brain images at 1.5T (TR, 142 ms; TE, 6 ms; section thickness, 4 mm; scanning time, 16 seconds) of a 28-week-old fetus without motion artifacts after a successful breath-hold (A) and with motion artifacts after an incomplete breath-hold (B). Breathing artifacts appear in the form of high-signal ghosts in the operator-selected phase-encoding direction and severely degrade image quality.
