Postmortem imaging in goats using computed tomography with air as a negative contrast agent.

ABSTRACT:

Purpose

Evaluation of the usefulness of air as a negative contrast medium of blood vessels in goats in post mortem computed tomography (PMCT) and establishing the protocol with appropriate doses and timing of the contrast medium administration.

Methods

Thirty three goats were euthanized 10 to 300 min before the study. First, in 3 goats air was administered into the left or right common carotid artery at dose of 60, 100 and 120 ml/kg, and after each dose PMCT was performed in lateral recumbency. As the latter dose proved to visualize blood vessels best, following 30 goats were examined in the same manner but only with the use of air dose of 120 ml/kg. The quality of CT scans was evaluated independently by two board-certified radiologists.

Results

In all studied animals
