Spiral CT scanning of the paranasal sinuses.
نویسندگان
چکیده
Because of the interest in reducing the time and radiation required for screening sinuses with CT, we compared the quality of conventional coronal CT images with coronally reconstructed, axially acquired spiral CT images. The spiral reconstructions compared favorably with the conventional images and had significantly less motion and dental amalgam artifacts.
