Brief Summary

1\. Objective to compare the effect of single energy imaging and mar technology in reducing artifacts of knee and hip replacement, and to explore the appropriate keV range of Mar technology in removing metal artifacts.,2. Objective to compare the effects of different MRI sequences (mavric / semac, stir, ideal, FSE) in removing artifacts of spinal internal fixation, knee and hip replacement.
