뇌혈관 자기공명영상에서 Time-of-flight(TOF) 기법을 이용한 영상의 질 평가 : 1.5 T 와 3.0 T 자기공명영상 비교
The Evaluation of Image Quality using Time of Flight in Intracranial Magnetic Resonance Imaging : Comparison with 1.5 T and 3.0 T
Intracrnial 3D TOF MR angiography was performed in 30 normal volunteers with both 1.5 and 3.0 T MRI system with high resolutions. Used Voxel sizes were 0.39 x 0.39 x 0.2(1.5 T) and 0.19 x 0.19 x 0.35(3.0 T), respectively. High image quality and depiction of small vessel branches were equality demonstrated with 1.5 T and 3.0 T HR TOF MRA(p<0.05). Intracranial high resolution TOF MRA with 1.5 T and 3.0 T provides high diagnostic information with having merits and demerits in depiction of vascular branches.
