Editor’s picks (EIC comments) This article reports that the Gd-containing contrast media distribution in the CSF space including peri-vascular spaces. The findings are very important for recent topic not only about accumulation of Gd-containing contrast media but also about the glymphatic system in the brain. This article is selected as the Top-1%-cited one in the Web of Sciences by Clarivate analytics. It is a so hot and exciting article.
(Author's comments) Neural fiber tractography is one of the useful clinical applications of diffusion tensor imaging (DTI). We sought an optimal threshold of fractional anisotropy (FA), a standard metric derived from DTI, when depicting tractograms of the corticospinal tracts in the brain. We carried out a tract-specific analysis of normal and diseased corticospinal tracts by ischemic stroke. Our results suggested that optimal FA threshold values may be around 0.20. We had an opportunity to carry out this study at the beginning of clinical use of DTI and are now privileged to introduce our paper as one of the most cited papers.
(Author’s comments) In early 2000s, several reports showing the utility of diffusion weighted imaging (DWI) for detecting breast cancer had emerged. DWI had been focused because it can visualize the breast cancer with high contrast without contrast material. In our article, we try to evaluate how accurate the DWI can demonstrate distribution of breast cancer. DWI of the breast is more challenging than that of other organs due to the convex shape, the air surrounding the breast, and rich fat tissue. These issues has been improving due to progression of hardware including multichannel coil and higher gradient and parallel imaging. However, there are still some limitations exist. Currently, there are two directions of breast DWI in which screening and evaluation of biological characteristics. To accomplish both, better spatial resolution, higher signal to noise ratio, stable imaging quality, and repeatability has to be obtained.
