Transabdominal ultrasound TAU and also the transvaginal ultrasound TVU are valuable diagnostic tools in obstetrics and gynecology.

Transabdominal ultrasound cannot reliably diagnose pregnancies that are less than 6 weeks gestation. Prompt diagnosis made possible by transvaginal ultrasound can, therefore, result in earlier treatment.
