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.
