Figure 1

Examples of artifacts due to the presence of stainless steel screws in (a) gradient echo image with ±62.5 kHz receive bandwith and (b) spin echo image with ±16 kHz receive bandwidth. Solid arrows show signal loss that can be due to dephasing, or from signal being shifted away from a region. The dotted arrow shows geometric distortion of the femoral condyle. Dashed arrows show signal pile-up, which can be a combination of in-plane and through-slice displacement of signal from multiple locations to one position.
