EPR imaging allows visualizing free radicals in small animals and gives information of redox status in various tissues. However, the determination of the position is difficult due to the lack of anatomical information. So far to solve this problem, co-registration of an EPR image and a high field MRI image has been applied. However, the cost of the high field MRI system may be obstacle for many researchers to access this method. The purpose of the present work was developing a compact low field MRI system running on a same magnetic circuit used for a 750 MHz EPR imaging system.
