We have developed a new and simplified injection technique based on a
mixture of latex and lead oxide. This injection technique is unique in
its possession of both color and radio-opacity. We have developed and
refined this methodology in rats, and have demonstrated it to possess
superior qualities of injectability. Depiction of small vessels is hi
ghly detailed both radiographically and grossly. (C) 1997 Wiley-Liss,
