This research is conducted to identify whether an m-DIXON technique which is useful for an abdomen MRI examination compared with an existing e-THRIVE technique is a clinically useful or not. There was evaluated quantitative and qualitative to 84 subjects who had abdomen MRI exam due to their liver disease were conducted during a period from September in 2013 to February in 2014. First of all the quantitative evaluation, the m-DIXON technique's SNR was 90.42±16.90 and the e-THRIVE technique was 60.42±11.54 and the m-DIXON technique's CNR was 52.38±22.58 and the e-THRIVE technique was 46.31±20.25. Secondly in the qualitative evaluation, the m-DIXON technique's image quality was 4.06±0.34, a artifact was 3.64±0.22, and fat suppression was 4.16±0.15, the e-THRIVE technique's image quality was 3.14±0.35, a artifact was 3.06±0.38, fat suppression was 3.14±0.30. In conclusion, m-DIXON technique for abdomen MRI examination showed superiority over both SNR as a quantitative anaylsis, CNR and a qualitative analysis.

이 연구의 목적은 복부 MRI검사에 유용한 m-DIXON기법이 기존 e-THRIVE기법에 비해 임상적으로 유용한 검사인지 알아보기 위해 2013년 9월부터 2014년 2월까지 간 질환을 주소로 복부 MRI검사를 시행한 84명을 대상으로 분석하였다. 연구결과에서 SNR은 m-DIXON기법 90.42±16.90, e-THRIVE 60.42±11.54로 나타났으며, CNR은 m-DIXON기법 52.38±22.58, e-THRIVE기법 46.31±20.25로 나타났다. 정성적 평가는 m-DIXON기법에서 영상의 질 4.06±0.34, 인공물 3.64±0.22, 지방소거 4.16±0.15로 나타났으며, e-THRIVE기법에서 영상의 질 3.14±0.35, 인공물 3.06±0.38, 지방소거 3.14±0.30으로 나타났다. 결론적으로 복부 MRI검사에서 m-DIXON기법은 e-THRIVE 기법에 비해 정량적 평가 및 정성적 평가에서 우수한 것으로 나타나, 향후 복부질환의 진단에 유용하게 활용할 것을 제안한다.
