Abdominal ultrasonography is widely applied in cancer screening and/or health checkups, but the quality of screening ultrasonography has not always been well controlled. Recently, three medical societies—the Japan Society of Ultrasonics in Medicine, the Japanese Society of Gastrointestinal Cancer Screening, and the Japan Society of Ningen Dock—jointly published the Manual for Abdominal Ultrasound in Cancer Screening and Health Checkups. This manual is composed of two parts. The first part is Standard Procedure for Abdominal Ultrasound Cancer Screening, and the second is Categorized Criteria for Abdominal Ultrasound Cancer Screening. We expect the manner of screening ultrasonography to be standardized, and its quality well controlled at a high level, based on the propagation of this manual. Also, we hope the efficacy of abdominal ultrasound cancer screening for decreasing cancer mortality will be confirmed in the near future.
