Cerebral angiography of the rat. Technical note.

An open technique of right retrograde brachial arteriography of the rat is described. With the aid of magnification radiography, this method permits high quality examinations of the extracranial and intracranial circulations. The muscular branches of the brachial artery are preserved at the initial study to allow repeat examination. A four-vessel study is also attainable by injection of contrast material immediately after death of the animal.
