To assess the potential of existing MRI scanner performance to evaluate novel model animal species cardiac MRI was performed on large spiders. The acquired images were used to extract the first direct in vivo measurements of cardiac function in this type of animal. Measurements revealed a previously unknown relationship between animal mass and cardiac ejection fraction.
