Abstract

We evaluated the usefulness of $DTI_{6D}$ which was acquiring six direction diffusion data through compared to $DWI_{3D}$. Mean SNR and CNR were on $DWI_{3D}$ and $DTI_{6D}$ $44.01{\pm}13.36$, $37.15{\pm}11.44$ (p=0.029) and $18.47{\pm}9.66$, $19.88{\pm}9.20$(p=0.017). The number of lesions were $311{\pm}26.87$, $224.5{\pm}26.16$(p=0.041) on $DTI_{6D}$ and $DWI_{3D}$. Twenty patients were the more detected brain infarction lesion on $DTI_{6D}$. But there is no one the more detected on $DWI_{3D}$. And the more three direction diffusion data could get more information. However, we need to consider about the time consumption compared to DWI.

본 연구은 $DWI_{3D}$와 비교하여 6방향의 확산영상을 획득하여 $DTI_{6D}$의 유용성을 평가하고자 한다. 뇌 허혈성질환의 진단을 받은 환자 42명을 대상으로 1.5T 자기공명영상장치(Excite HD, GE, USA)를 이용하여 검사를 하였다. 사용된 펄스시퀀스는 $DWI_{3D}$와 $DTI_{6D}$를 사고하였고, 두 $DWI_{3D}$ and $DTI_{6D}$에 관하여 평균 신호대 잡음비 와 대조도대 잡음비는 $DTI_{6D}$ $42.82{\pm}14.79$, $37.15{\pm}11.43$ (p=0.029) and $18.47{\pm}9.59$, $19.88{\pm}9.10$(p=0.017)이었다. 병소에 수는 $DTI_{6D}$ and $DWI_{3D}$에 관하여 305, 219(p=0.041) 이었다. 총42명의 환자 중 20명의 환자에 대하여 $DTI_{6D}$가 뇌경색(brain infarction)부분에 대하여 더욱더 많은 병소부분이 검출되었다. 그리고 3방향이상의 확산영상은 더욱더 많은 뇌 허혈성지환의 영상정보를 제공하였다. 그러나, 임상적으로 $DWI_{3D}$와 비교했을 때 긴 검사 시간에 대하여 고려할 필요가 있다.
