Lateral scout radiograph in CT-guided aspiration biopsy

Easy, accurate,and rapid determination of needle-tip location is readily accomplished on any CT scanner with lateral scout radiograph capability. After needle placement, a lateral scout radiograph is obtained and the needle tip can be seen. A single CT section is then obtained at precisely the level of the tip. Aspiration can then be performed if needle placement is appropriate. If the needle lies outside the desired site, it can be easily repositioned
