SEMAC and CS-SEMAC sequences effectively reduced total geometric distortion by 79%, improving MRI accuracy.
TSE sequence showed the highest geometric distortion (2187±297 mm), indicating poorer performance compared to SEMAC.
Directional dependency of distortion was noted, being most pronounced along the frequency-encoding axis.
Metal artifacts significantly impact MRI spatial accuracy, highlighting the importance of sequence selection.
