title: A modified technique to obtain uniform precipitation of lanthanum tracer in the extracellular space.
abstract: A method for obtaining a uniform, dense precipitate of lanthanum nitrate to delineate extracellular space is described. Improvement of the previous technique is achieved by phosphate precipitation of lanthanum in the tissue carried out at low temperature. This method has been successfully applied to bone marrow.
