Ultrasonic evaluation of trophoblastic disease and the response to chemotherapy.

Ultrasound is an established method of confirming the presence of a hydatidiform mole in utero. However, in agreement with other investigations, we have often noted that the appearance of this entity is less specific than originally reported. To elucidate this, the ultrasonic patterns of 26 patients with trophoblastic disease and 27 with other entities were reviewed.

Ultrasonographic in utero identification and measurement of the normal fetal spleen.

Sixty-nine ultrasonographic examinations were performed to identify and measure the fetal spleen in utero on 49 women with regular menstrual cycles, at 18-41 weeks of gestation. The length (FS-L), width (FS-W), area (FS-A), and sectional area (length X width; FS-LW) of the fetal spleen correlated well with the gestational age. A very high correlation of FS-LW with FS-A was noted (r = 0.

Ultrasonographic measurement of the human fetal liver in utero.

A total of 232 measurements of the size of the human fetal liver were made from 19 weeks gestation through to term. The size of the liver increased linearly with the advance in pregnancy. Statistical analyses showed a highly significant correlation between liver circumference and area and gestational week or fetal abdominal circumference (r = 0.
