Patient's question:
How many weeks of pregnancy can an ultrasound detect?Doctor's answer:
Hello, ultrasound can determine the date of pregnancy, but since ultrasound is also a manual operation, there is some margin for error. The earliest a gestational sac can be seen on ultrasound is around 35 days, and it is generally visible around 40 days. However, because the embryo is still small, it is not possible to clearly observe the projection through ultrasound. It is usually clearer to see it around 6-7 weeks.
