超音波検査が検診（健診）に用いられるようになって約30年が経過した．しかし，未だに充分な評価がなされていない．検診に超音波検査を導入する目的の第一は，がんの早期発見と考えられることから，ここではがん検診を中心に実施体制，がん検診を行なうための条件，評価法，精度管理，受診者とのコミュニケーションなどについて概説する．

Approximately 30 years have passed since ultrasonography came to be used for health check-ups and mass surveys of the upper abdomen. However, its efficacy has not yet been adequately evaluated. The most important purpose for introducing abdominal ultrasonography into screening is considered to be the early detection of cancers. This presentation outlines enforcement of cancer screening, conditions for performing cancer screening, evaluation methods of cancer screening, accuracy of the screening test, accuracy of the screening system, and communication with the examinee.
