The purpose of our study was to determine the optimal concentration of a gadolinium-based contrast agent (gadodiamide) for direct MR arthrography at 3 T compared with 1.5 T in an in vitro study.
Optimized concentrations of gadolinium-based contrast agents for MR arthrography are similar at 3 and 1.5 T, although a slightly greater dilution may be useful at 3 T. Signal-to-noise ratio peak levels are significantly reduced by adding an iodinated contrast agent, relatively significantly more at 3 T than at 1.5 T.
我们研究的目的是在一项体外研究中，确定钆基造影剂（钆双胺）在3T时与1.5T时用于直接磁共振关节造影的最佳浓度。
用于磁共振关节造影的钆基造影剂的优化浓度在3T和1.5T时相似，尽管在3T时稍大的稀释度可能有用。添加碘化造影剂会显著降低信噪比峰值水平，在3T时比在1.5T时降低得相对更显著。
