摘要：
The original design of the Eurospin test objects (Magn. Reson. Imaging 6:195-199; 1988) for the assessment of magnetic resonance imaging (MRI) image quality, was subjected to re-evaluation at several meetings during the subsequent years, culminating in some changes to the designs. Further, an annulus filled with saline was added to the set with the purpose of simulating the loading of the receiver coils normal in clinical use. All of these modified test objects were circulated among 8 European centres in a detailed experimental trial of their utility. The results are presented, indicating increased success and enhanced functionality of this set of test objects.
