Manganese is known to affect relaxation times. Blueberry is naturally rich in manganese, and oral contrast effect by its squeezed juice (B. J) was expected. At some appropriate concentration of manganese within daily intake level, B. J worked as positive contrast agent on T1WIs and negative one on T2WIs simultaneously without any side effects. The negative effect on T2WIs could reduce ghost artifacts from motion of high intensity structures. B. J improved confirmation of gastroduodenal tract regardless of field strength and could be adapted for fast SE. We introduced a preliminary examination of B. J as an oral contrast agent for upper abdominal MRI.
已知锰会影响弛豫时间。蓝莓天然富含锰，因此预计其榨汁（B.J.）会产生口服对比效果。在每日摄入量范围内的某些适当锰浓度下，B.J.在T1加权成像（T1WIs）上作为阳性对比剂，同时在T2加权成像（T2WIs）上作为阴性对比剂，且无任何副作用。对T2WIs的负面影响可减少高强度结构运动产生的鬼影伪影。无论场强如何，B.J.都能改善胃十二指肠的显影，并且可用于快速自旋回波序列（fast SE）。我们介绍了将B.J.作为上腹部磁共振成像（MRI）口服对比剂的初步检查。
