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.
