The departure from the 1:1 ratio in the amounts of La and Gd determined in the investigated tissues has been used to gain information on the role of the complex stability and "wash-out" kinetics. The behavior of the less s` La-DTPA highlights processes occurring for Gd-DTPA at a slower rate.The herein obtained results support the view that most of the La/Gd retained in the brain arises from the intact chelate that has extravasated immediately after the intravenous administration. Long-term deposition of metal ions from internal reservoirs seems particularly relevant for liver and spleen.
