Comparison of frequency selective (A), short tau inversion recovery (STIR) (B), and DIXON (C) fat suppression techniques in a 32 year old male subject with an anterior cruciate ligament reconstruction and a titanium interference screw in the femoral tunnel (arrow) and a stainless steel button on the anterior aspect of the tibia (arrow head) to secure the implanted graft. The presence of metallic hardware generates local Bo inhomogeneities, causing local failure of frequency selective fat suppression techniques. STIR imaging has greater uniformity of fat suppression near the implanted hardware, with the reduction of image signal-to-noise ratio. Note the DIXON technique has slightly more artifact (arrowhead) than STIR but less than the frequency selective fat suppression.
