Abstract
Methods and compositions are disclosed for enhancing .sup.19 F magnetic resonance imaging which utilize trifluoromethyl derivatives of iodinated X-ray contrast media. Typical magnetic resonance contrast media within the scope of the present invention include bis(trifluoromethyl)benzene derivatives, tris(trifluoromethyl)benzene derivatives, tetrakis(trifluoromethyl)benzene derivatives, and other related trifluoromethylated benzene derivatives.
