Organ weight: a new tissue parameter to assess water proton spin-lattice relaxation time.
Organ weight has not been considered as a parameter in tissue relaxometry to account for the dependency of spin-lattice relaxation time. Results presented here indicate that, as the organ weight increases, the spin-lattice relaxation time decreases. Furthermore, this relationship has an allometric function, an indication that the metabolic characteristic (oxygen consumption) of the organ is indeed dependent on organ weight and in turn influences spin-lattice relaxation time.
