Abstract
The clay minerals kaolin and bentonite are demonstrated as gastrointestinal contrast agents for MRI. Weak field dependence of the relaxation efficiency assures effectiveness of these agents at all field strengths in clinical use. These agents eliminate signals from their immediate environment and are not toxic.
摘要
粘土矿物高岭土和膨润土被证明可作为磁共振成像（MRI）的胃肠道造影剂。弛豫效率对场强的依赖性较弱，确保了这些造影剂在临床使用的所有场强下均有效。这些造影剂可消除其紧邻环境中的信号，且无毒。
