Quantitative analysis of the skull in the Japanese wolf (Canis lupus hodophilax) using CT.
In this study using computed tomography (CT), the volumes of the internal cranial cavities, such as the braincase, frontal sinus and tympanic cavity, and the ratio of the volume of each cavity to the skull volume in Japanese wolves were quantified, and CT images of the frontal sinus were observed.
