[Echographic transvaginal diagnosis of pregnancy in the first trimester]

A comparative analysis of informative value of transvaginal echography and transabdominal scanning was made when 86 pregnant females were investigated in the first trimester of pregnancy. It was established that transvaginal echography could provide the investigator with a more precise and earlier assessment of pregnancy development its initial stages. If transabdominal scannings informative value turned to be insufficient, the usage of transvaginal echography in the determination of pregnancy itself and pregnancy-associated complications was found mandatory.
