Can ectopic pregnancy be detected by abdominal color Doppler ultrasound?

Ectopic pregnancy can be seen by abdominal color Doppler examination, but if the pregnancy time is less than 6 weeks, it is generally impossible to check out. Usually, it is necessary to hold urine before the examination and keep the bladder full to facilitate better observation of the uterus. If the fertilized egg is implanted on the endometrium, it can basically rule out ectopic pregnancy.
