title: Sonoembryology: an organ-oriented approach using a high-frequency vaginal probe.
abstract: First trimester gestations of 95 patients were studied by high-frequency transvaginal sonography, which permits the imaging of organs shortly after their development. This new technique has great potential for clinical implementation in such cases as accurate gestational dating and malformation workup.
