Using biplanar fluoroscopy to guide radiopaque vascular injections: a new method for vascular imaging.

Studying vascular anatomy, especially in the context of relationships with hard tissues, is of great interest to biologists. Vascular studies have provided significant insight into physiology, function, phylogenetic relationships, and evolutionary patterns. Injection of resin or latex into the vascu...
