CT scanning is more sensitive and better at detecting<unk> han X-rays are,  and often reveals multiple<unk> s in cases where chest X-ray showed only a contusion. Before CT scanning was widely available,<unk><unk>  was considered unusual because it was not common to find with X-ray alone. On a CT scan,<unk><unk> s show up in a contused area of the lung, typically appearing as cavities filled with air or fluid that usually have an elliptical or ovoid shape. The roundness of the cavity is due to the elasticity of the lung.
