The use of lead methacrylate 2-ethylhexanoate to create a radio-opaque resin suitable for microvascular corrosion casting.
A radio-opaque methacrylate-based resin suitable for microvascular corrosion casting can be prepared by substituting lead methacrylate 2-ethylhexanoate for a proportion of the methyl methacrylate monomer normally used. Best results are achieved when conventional methacrylate resin is injected first to fill the vascular tree, and this is chased with the radio-opaque resin. The pattern of arterial and arteriolar distribution can then subsequently be followed by means of a radiographic survey of the cast, and this is of value prior to sampling from vascular systems which show functional subdivisions that cannot be correlated with any surface features. The radio-opacity of the resin and the quantity injected can be varied easily to suit individual requirements.
