Abstract
A significant problem for whole body PEDRI is the absorbed RF power in the body. In this paper the optimal pulse and field strength are dete rmined which maximize the signal to noise ratio for a certain RF power level. Our calculations show that the relaxation times of the free ra dical contrast agent are the dominating factors which determine the pu lse sequence and main field strength.
