摘要

在目前的工作中，我们研究了趋磁细菌和生物源磁铁矿纳米晶体作为磁共振成像中潜在的造影剂的效率。测试包括对两种由趋磁细菌和磁小体在相同浓度下制备的磁性颗粒悬浮液的横向和纵向弛豫测量。我们观察到磁性粒子的存在大大减少了横向弛豫时间。另一方面，仅检测到对纵向时间的影响很小。

Magnetotactic bacteria and biogenic magnetite nanocrystals as potential contrast agents in magnetic resonance imaging

In the present work we examine the efficiency of magnetotactic bacteria and biogenic magnetite nanocrystals as potential contrast agents in magnetic resonance imaging. The tests include transverse and longitudinal relaxation measurements on two suspensions of magnetic particles prepared with magnetotactic bacteria and magnetosomes at the same concentration. We observed a strong reduction of the transverse relaxation time by the presence of magnetic particles. On the other hand, only a small influence on the longitudinal time is detected.
