Summary
Transvaginal ultrasound scan (TVS) is the recommended method for assessing pregnancies in the first trimester. Transabdominal scanning can be performed if women are reluctant to have a TVS, but the limitations of this method over TVS should be explained. Examination with TVS provides a detailed evaluation of the endometrial cavity and ovaries, but the high-frequency transducer that allows improved near-field resolution compared with transabdominal examinations suffers from limited sound penetration (far-field imaging). The vaginal probe, due to its proximity to the uterus, allows excellent views of the uterus and pelvis in order to view and measure the gestational sac and any embryonic structures, which are small in the first trimester.
