A tissue phantom for diffusion-weighted imaging was developed, basing its contrast between two compartments on different apparent diffusion coefficients, without contrast due to T2 relaxation and proton density. These contrast properties of the phantom simulate the situation found in normal gray matter and areas of acute ischemia. A possible application of the phantom was demonstrated for the investigation of the accuracy of volume measurements based on diffusion-weighted images.
开发了一种用于扩散加权成像的组织体模，其两个腔室之间的对比度基于不同的表观扩散系数，不存在因T2弛豫和质子密度产生的对比度。该体模的这些对比度特性模拟了正常灰质和急性缺血区域中的情况。展示了该体模在基于扩散加权图像研究体积测量准确性方面的一种可能应用。
