Diffusion MRI
소개 (활용범위/ 관련 논문 참고한 사례)
DSI Studio는 Diffusion Spectrum Imaging (DSI) 데이터를 분석하는 데 사용되는 소프트웨어입니다.
DSI는 확산자기공명영상(Diffusion MRI)의 한 형태로, 확산텐서 이상의 정보를 제공하여 더 정교한 확산 방향 및 형태를 추정합니다.
DSI Studio는 확산텐서 트래킹 및 다양한 확산 연구 분석을 지원합니다. 아래는 DSI Studio를 사용하여 국제전문학술지 논문에 게재된 결과 입니다.
분석결과
Fig. Basal ganglia segmentation involved in Parkinson’s disease. Left represents segmentations overlaid on top of MNI template, right represents an example segmentation of a PD subject used in this study (Patient 3127), overlaid on the same subject’s T1w image. Structures segmented are left and right putamen, caudate, nucleus accumbens (NA), globus pallidus externus (GPe), globus pallidus internus (GPi), substantia nigra pars compacta (SNc), substantia nigra pars reticula (SNr), subthalamic nucleus (STN), parabrachial pigmented nucleus (PBP), ventral tegmental area (VTA).
Fig. Connectivity matrices of FDR corrected FA p-values, RD p-values and HC, PD fiber counts. Top two matrices represent FDR corrected p-values of t-test comparisons between HC and PD, with colors closer to red being less significant and colors closer to blue being more significant. Bottom two matrices represent fiber counts between each pair of HC segmentations and each pair of PD segmentations. Colors closer to red represent more numerous fibers and colors closer to blue represent less numerous fibers.
