A trial was carried out in which the protocols and prototype test objects developed under a European Economic Community concerted research project for the assessment of MR imaging equipment were tested in a series of commercial imaging systems situated throughout Europe. In general, many imperfections were discovered in the imaging performance of the scanners and, in particular, the accuracy and precision with which the relaxation times T1 and T2 could be measured from the images were found to be rather disappointing.
开展了一项试验，在该试验中，对欧洲经济共同体一项关于磁共振成像设备评估的协同研究项目所开发的方案和原型测试对象，在遍布欧洲的一系列商用成像系统中进行了测试。总体而言，在扫描仪的成像性能方面发现了许多缺陷，特别是从图像中测量弛豫时间T1和T2的准确性和精确性，结果令人相当失望。
