We studied mouse liver, heart and kidney for possible diurnal fluctuations of T1 and T2. In a subgroup of animals, we attempted to relate T1 and T2 of the organ samples to their water and lipid content (and in the liver, also to glycogen content). Diurnal periodic fluctuation was found only in liver T2 and was of a very minor degree. Regression analysis of organ T2 estabilished relationships with chemical composition which explained 25%-40% of the observed variation in T2. No relationship with T1 could be established.
