Abstract

The purpose of this study is to know clinical usefulness for fat suppression of the body curved portion compared with TSE-CHESS and TSE-SPAIR technique. A total of 25 normal volunteers without cervical spine disease were studied on a 3.0 T MRI scanner. As a quantitative analysis, PSNRs and CNRs were evaluated by using two methods for fat suppression of the body curved portion. As a results, PSNRs and CNRs for fat suppression were significantly greater for the TSE-SPAIR technique compared to TSE-CHESS technique. In conclusion, this study showed that a TSE-SPAIR technique has improved PSNRs and CNRs for evaluating of fat suppression in the body curved portion. These conclusions in the future will be provided information in diagnosis of fat suppression for the body curved portion.

본 실험의 목적은 TSE-CHESS 지방소거와 TSE-SPAIR 지방소거 기법을 비교하여 인체굴곡부위 지방소거에 있어서 TSE-SPAIR 기법의 임상적 유용성을 알아보고자 하였다. 총 25명의 경추질환이 없는 정상인을 대상으로 3.0 T MRI 기기를 이용하여 검사를 하였고, 사용된 두 기법에 대한 인체굴곡 부위 지방소거에 대한 정량적 분석으로 PSNR과 CNR을 평가하였다. 실험결과로 굴곡부위에 대한 PSNRs 과 CNRs 값은 TSE-SPAIR 기법이 유의성 있는 결과를 얻었다. 결론적으로, TSE-CHESS 지방소거와 TSE-SPAIR 지방소거 기법을 비교했을 때, 인체굴곡 부위에 대한 지방소거 평가에서 증가된 PSNRs 과 CNRs 값을 얻었다. 이러한 결과는 향후 인체굴곡 부위 지방소거 진단에 유용성 있는 정보를 제공 할 것이다.
