MRI of patients with hip prostheses remains a challenge,
particularly at 3T. Through phantom and volunteer
studies, a set of optimized protocols for metal artifact
reduction (MAR) using view angle tilting (VAT) and slice
encoding metal artifact correction (SEMAC) was found to
produce diagnostic information within a clinically
acceptable scan time at 3T. For prostheses made of
non-magnetic alloys, the degree of MAR approaches that
of 1.5T.
