Expert Differential Diagnoses: Obstetrics(DDX)

Part of the brand-new Expert Differential Diagnoses series, this unique print-and-electronic reference will guide
radiologists toward logical, on-target differential diagnoses based on key imaging findings and clinical information.
The book presents the most useful differential diagnoses in obstetrics, grouped into sections on first trimester, fetal
anatomic abnormalities, multiple gestations, placenta/membranes, umbilical cord, amniotic fluid, fetal growth and well-
being, uterus-cervix, maternal conditions in pregnancy, and postpartum complications. Each differential diagnosis
includes at least eight clear, sharp, succinctly annotated images; a list of diagnostic possibilities sorted as common,
less common, and rare but important; and brief, bulleted text offering helpful diagnostic clues.

The companion online Amirsys® e-Book Advantage™ provides additional annotated images.
