In addition, the intercellular contrast agent MnCl2 has been successfully used to assess cell viability in heart ischemia [3], and cells can be easily labeled using Mn2+ in vitro [4]. Hasegawa et al. reported that MEMRI can reflect MnSOD over-expression in a tumor model [2]. Radiotherapy using high-energy x-rays treats malignancies with the intention of destroying or inactivating cells while preserving normal tissue integrity. We investigated the relationship between x-ray irradiation and Mn uptake in tumor cells and tested whether MEMRI can detect radiation-induced cell disturbances at an early stage both in vitro and in vivo., ISMRM 19th Annual Meeting}, title = {In-vivo detection of cell cycle arrest using manganese-enhanced MRI (MEMRI)}, year = {2011} }
