The hospital can do ultrasound on weekends, as long as the ultrasound department has a doctor on duty can do. The general situation of weekend ultrasound examinations is like this: 1. individual hospitals, the director does not attend the weekend, and young doctors attend more. 2. there are individual examination items, ultrasound department does not do on weekends, depending on the requirements of their own hospital departments. 3. like some new technologies, including ultrasonography, intervention, etc., individual hospitals do not do on weekends. It is necessary to consult the hospital where you are going to be examined, as the rules vary from hospital to hospital. In addition, there are many patients in the ultrasound department of large hospitals, so it is not always possible to have a test on the same day. To be on the safe side, it is recommended to consult and make an appointment first.
