摘要
En 中文
Although over the last 20 years diffusion MRI has become an established technique with a great impact on health. care and neurosciences, like any other MRI technique it remains subject to artifacts and pitfalls. In addition, to, common MRI artifacts, there are specific problems that one may encounter when using MRI scanner gradient hardware for diffusion MRI, especially in terms of eddy currents and sensitivity to motion. In this article we review those artifacts and pitfalls on a qualitative basis, and introduce possible strategies that have been developed to mitigate or overcome them.
