Abstract
Objective. This study was designed to compare diagnostic quality of MR imag es of patients with spinal hardware acquired using a conventional T1-weight ed spin-echo sequence and a new metal artifact reduction sequence (MARS). Conclusion. The new MARS sequence effectively reduces the degree of tissue- obscuring artifact produced by spinal fixation hardware and subjectively im proves image quality compared with the conventional T1-weighted spin-echo s equence.
