국문 초록
본 연구에서는 magnetic susceptibility artifact의 방향성에 따른 artifact의 길이와 면적을 정량적 평가를 하였다. 자체 제작한 magnetic susceptibility artifact phantom을 이용하였고, 3.0T MRI system에서 T2 FSE를 이용해 axial, coronal, sagittal에서 frequency encoding direction 변화를 주었다. 연구 결과 axial에서는 AP에서 RL로, coronal에서는 RL에서 SI로, sagittal에서는 AP에서 SI로 frequency encoding방향을 변환하였을 때 모두 길이 차이가 발생한 것을 확인할 수 있었다(p<0.05). 또한 frequency encoding방향 변환에 따른 magnetic susceptibility artifact area를 측정하였을 때 차이가 발생함을 확인할 수 있었다(p<0.05). 하지만 다양한 종류의 screw와 plate가 사용되는 나사 고정술을 고려하였을 때 향후 다양한 종류의 screw와 plate를 대상으로 magnetic susceptibility artifact의 추가 연구가 필요할 것이며, 이에 본 연구가 나사 고정술로 발생하는 magnetic susceptibility artifact를 방지하는 연구에 기초자료로 사용될 것이라 사료된다.
