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.
