This second edition offers a unique and focused study of the use of RADIOLOGIA during the first trimester, a critical time in a fetus development. It includes basic examination guidelines as well as cutting-edge RADIOLOGIA modalities, including Doppler and three-dimensional RADIOLOGIA, for the period immediately preceding conception through early embryology. Fully updated, the text begins with a discussion of the safety and efficacy of diagnostic RADIOLOGIA and the use of this modality for the evaluation and treatment of infertility. Recognized experts in the field then explore conditions that may interfere with normal conception or development, including maternal diseases that would benefit from early scanning, elements of teratology, multiple gestations, ectopic pregnancy, gestational trophoblastic disease, fetal anomalies and invasive procedures in the first trimester.
