小鼠大脑的高分辨率MRI在估计神经解剖学随时间的变化以了解正常发育以及疾病过程和机制方面越来越突出。这些类型的实验,其中时间的变化是尽可能准确地捕捉使用成像,面临着多个实验设计的选择。这些选择中的主要是是否在体外成像,其中上级分辨率和对比度是可用的,或者在体内成像,其中分辨率和对比度较低,但是可以纵向跟踪动物。在这里,我们探索这种权衡,首先估计来源的变异性解剖小鼠MRI,然后,使用统计模拟,这些实验设计的选择提供功率分析。
High-resolution MRI of the mouse brain is gaining prominence in estimating changes in neuroanatomy over time to understand both normal developmental as well as disease processes and mechanisms. These types of experiments, where a change in time is to be captured as accurately as possible using imaging, face multiple experimental design choices. Chief amongst these choices is whether to image ex-vivo, where superior resolution and contrast are available, or in-vivo, where resolution and contrast are lower but the animal can be followed longitudinally. Here we explore this tradeoff by first estimating the sources of variability in anatomical mouse MRI and then, using statistical simulations, provide power analyses of these experiment design choices.
