MRI around metallic implants such as total joint replacements has been limited due to artifacts. Recently a new method for reducing artifact near metal called Slice Encoding for Metal Artifact Correction (SEMAC) was described. This work compares the clinical performance of SEMAC versus 2D-FSE in an initial population of symptomatic patients with metal implants. Clinical management was changed in a substantial number of cases.
