Preparation technique and new contrast medium for radiography of biologic specimens.

An easily prepared contrast medium for radiography of vascular and ventricular systems is described. The accompanying fixation methods are discussed. Utilizing a few, readily available components and chemicals, technologists should be able to easily prepare a contrast medium that will produce, both before and after preservative tissue fixation, a quality specimen for radiography. The methods are easily applicable to most biological specimens.
