초록

본 실험의 목적은 2D TSE-SPIR 와 3D FFE-PROSET 기법을 비교하여 관절연골 묘출에 있어서 3D FFE-PORSET 기법의 임상적 유용성을 알아보고자 하였다. 2013년 1월부터 9월 까지 정상인(30명, 남자:12, 여자:18, 연령분포: 35 ~ 55, 평균연령: 49.48)을 대상으로 Philips 3.0T MRI 기기를 이용하여 검사를 하였고, 사용된 두 기법에 대한 관절연골 묘출을 정량적 분석으로 SNR과 CNR을 평가하였다. 정성적 분석은 영상의 묘출도을 3 등급에 관하여 MRI 전문방사선사가 평가를 하였다. 결과로 관절연골에 대한 SNRs 과 CNRs 값은 2D TSE-SPIR(SNRs: 4.41, 71.63, 7.34, CNRs: 64.30, 58.41) 과 3D FFE-PROSET(SNRs: 8.40, 114.02, 9.53, CNRs: 104.49, 139.49) 기법을 비교 했을 때 3D FFE-PROSET 기법이 유의성 있는 결과를 얻었고, 영상의 질 또한 3D FFE-PROSET(2.40) 기법이 높게 나타났다(p=0.0021). 결론적으로, 3D FFE-PROSET MRI가 2D FSE-SPIR 기법과 비교 했을 때 관절연골에 대한 평가에서 증가된 SNRs 값과 CNRs 값을 얻은 것을 보여 주었으며, 이러한 결론은 향후 관절연골 진단에 유용성 있는 정보를 제공할 것이다.

The purpose of this study is to know a clinical usefulness for delineation of articular cartilage compared with 2D TSE-SPIR and 3D FFE-PROSET technique. From January 2013 to september 2013, a total of 30 normal volunteers(12 men and 18 women aged between 35 and 55 years; mean 49.48 years) were studied on a philips 3.0T MRI scanner. As a quantitative analysis, SNRs and CNRs were evaluated by using two methods for delineation of articular cartilage. As a qualitative analysis, image quality was evaluated by special radiological technologist of MRI for image delineation on a three grade. As a results, SNRs and CNRs for articular cartilage were significantly greater for the 3D FFE-PROSET(SNRs: 8.40, 114.02, 9.53, CNRs: 104.49, 139.49) technique compared to 2D TSE-SPIR(SNRs: 4.41, 71.63, 7.34, CNRs: 64.30, 58.41) technique, image quality also was higher for evaluation of 3D FFE-PROSET(2.40) technique(p=0.0021). In conclusion, this study showed that a 3D FFE-PROSET MRI has improved SNRs and CNRs for evaluating of the articular cartilage, these conclusions in the future will be provided useful information in diagnosis of articular cartilage.
