The directional effect of the frequency-encoding gradient on T2WI-STIR was different from the performance on the T1WI.
Fig.1 (a-b) Under the default window width and window level, the images show the artifacts, including the low (long arrow) and high (arrowhead) signal intensities. The screw without protons displays a low signal intensity (short arrow).
