As ultrasound (US) is less invasive and relatively easy to perform, it is widely used for oppotunistic cancer screenings and health checkups. It is also reported to be useful in early detection of carcinomas.

 However, standard procedures for US screenings, standardized criteria for US findings and standardised assesments have not been definitely specified previously. Therefore, accuracy and efficacy of US screening have not been evaluated previously.

 In 2014, the Japanese Society of Gastrointestinal Cancer Screening, the Japan Society of Ultrasonics in Medicine and the Japan Society of Ningen Dock have cooperated to publish the Manual for Abdominal Ultrasound in Cancer Screening and Health Checkups aiming to improve quality and evaluate efficacy of US screenings. The manual is composed of standard prodcedures, categorarized criteria and assesments.

 As categorarized criteria are determined in accordance with US findings, decision of adequite assessments is easy even for assesing physicians who are not majoring in US screenings.

 On the other hand, the mannual has some tasks to be resolved. As to the standard prceduers, operator's skill and recording sections are most important to improve and homogenize quality of US screenings. So, exemplary sections to be recorded and scanning maneuvers should be specified.

 Insufficient definition and classification of US findings and operators unaccustomed to categorized criteria may cause disadvantages such as false negative and false positive cases. To prevent those disadavantages, continuous revision and guidance for operators are essenntial.

 Furthermore, undergoing objective evaluations for scanning and diagnostic skills by third-party will also contribute to not only enhancing the accuracy of US screenings but developing reliable and excellent institutes.

 By conducting an electrocardiogram on a medical checkup, various information such as arrhythmia, myocardial abnormalities, and the possibility of respiratory disease can be obtained, leading to early detection and treatment of heart disease. Recently most cardiograms have an automatic diagnosis function. This is a very useful function, but there are also many problems that need improvement, such as the accuracy of measurement points and judgment when noise is mixed.

 In order to maintain the confidence of those who receive a general medical examination, the facility is required to be at a level where the electrocardiography to be performed is reliable. For that purpose, it is important to confirm the level of one's own facility by participating in the external quality control as well as internal quality control in the facilities

 The Japan Society of Health Evaluation and Promotion manages the accuracy of the electrocardiogram once a year, and 363 facilities participate in 2018, and most facilities received an excellent judgment. However, there are also differences in the situation depending on each facility, such as who and at what timing of the electrocardiogram determination and how to reflect the determination result in the examination result.
