MRI of nonferromagnetic ballistics (IMAGE)
Caption
Scout (A), T1-weighted spin-echo (SE) (B), T2-weighted SE (C), T2-weighted gradient-recalled echo (GRE) (TR/TE, 500/10; D), and T2-weighted GRE (TR/TE, 700/30; E) MR images show jacket hollow point .45 automatic Colt pistol bullet (Corbon) (1), solid lead .45 Long Colt bullet (Winchester) (2), full metal jacket (FMJ) automatic Colt pistol bullet (Winchester) (3), 5.56-mm FMJ bullet (Federal Ammunition) (4), #7 lead shotgun pellet (Winchester) (5), and 5-mm lead air gun pellet (Sheridan) (6). On all sequences, metallic artifact is minimal. Although metallic artifact increases or blooms with increased TR/TE in GRE images (D and E), amount of surrounding distortion is still minimal.
