Is a thoraco-lumbar spine AP&LAT And lumbo-sacral spine AP&LAT Is also a chest xray?? If not whats the diff??
It is not. a chest xray. The spine films use a narrower(collimated) xray beam so only the region of the spine is included. The part of the lungs next to the thoracic spine may be visualized, but most of the lungs and other structures of the chest wouldn't be seen. Also, the technique used for the spine is optimized to see bony structures, not lung tissue.
