Abstract

The purpose of this study is to know optimized fat suppression techniques for brachial plexus compared with STIR and SPAIR T1, T2 techniques. A total of 30 normal volunteers without brachial plexus disease were studied on a 3.0 T MRI scanner. As an analytical method, SNR, CNR, 4-point grading scale were evaluated by using three pulse sequences. As a quantitative analysis, the SNR, CNR for SPAIR T1 technique provided high value in branchial plexus roots (03.07, -2.25), branchial plexus trunks(06.70, 36.31)(p<0.05). As a qualitative Analysis, The visibility for delineation of brachial plexus, fat suppression, artifact was significantly better on SPAIR T1(3.2, 3.6, 3.4) technique(p<0.05).

상완신경총에서 STIR(short TI inversion recovery) 지방소거 강조영상과 SPAIR(spectral adiabatic inversion recovery) T2, T1 지방소거 강조영상기법을 비교 평가하여 최적의 지방소거 기법을 알아보고자 하였다. 총 30 명 상완신경총에 질환이 없는 정상인 지원자를 대상으로 3.0 T MRI 기기를 이용하여 검사를 하였고, 분석방법으로 세 기법에 대하여 SNR, CNR 및 4단계 점수로 평가를 하였다. 정량적 분석 결과로 SPAIR T1 기법에 대한 SNR, CNR 값은 상완신경총기시부($03.07{\pm}0.98$, $-2.25{\pm}0.54$), 상완신경총몸체($06.70{\pm}1.81$, $36.31{\pm}2.17$)에서 높은 값을 제공하였다 (p<0.05). 정성적 분석결과 상완신경총 묘출도와 지방소거 정도, 영상의 인공물은 SPAIR T1($3.2{\pm}0.70$, $3.6{\pm}0.51$, $3.4{\pm}0.10$)기법이 의미 있게 높게 나타났다(p<0.05).
