  schema:description "Radiation coming from deep inside the body has to pass through more tissue to reach the scanner's detectors than radiation from near the skin, so without correction, deep organs look falsely dim. Attenuation correction uses a separate scan (usually a CT) to fix this and make the image quantitatively accurate."@en ;
