The radiologic aspects of abortion are divided into 2 main categories: (1) sequelae of uterine dilatation and curettage; and (2) problems related to intraamniotic injection of saline.
The first category includes uterine synechiae (Asherman syndrome) and incompetence of the internal os, the roentgen features of which are described and illustrated.
In the second category, proper placement of the needle in the amniotic sac can be verified by the injection of water soluble contrast medium (amniography). Malpositions in the placenta, vascular system or peritoneal cavity are easily recognized and serious consequences can be averted. The diagnosis of hydatidiform mole is readily established.
The use of amniography in other areas of obstetrical diagnosis, the roentgenologic assessment of fetal age and the problem of therapeutic abortion because of exposure to ionizing radiation early in pregnancy are briefly discussed.
