MRI of spinal hardware: comparison of conventional T1-weighted sequence with a new metal artifact reduction sequence

S D Chang et al. Skeletal Radiol. 2001 Apr.

Abstract

Objective: This study was designed to compare diagnostic quality of MR images of patients with spinal hardware acquired using a conventional T1-weighted 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 improves image quality compared with the conventional T1-weighted spin-echo sequence.
