Role of the 3-Vessel and Trachea View in Antenatal Detection of Tetralogy of Fallot.

Prenatal diagnosis of tetralogy of Fallot remains less frequent compared to other major congenital heart defects. In this study, we examined how often the 3-vessel and trachea view was abnormal in a large series of prenatally diagnosed cases of tetralogy of Fallot. In addition, we compared its sensitivity to that of the traditional outflow tract views for detection of tetralogy of Fallot.

Is the "I-Sign" in the 3-Vessel and Trachea View a Valid Tool for Prenatal Diagnosis of D-Transposition of the Great Arteries?

Prenatal diagnosis of D-transposition of the great arteries remains less frequent compared to other major congenital heart defects. In this study, we examined how often the 3-vessel and trachea view was abnormal in a large series of prenatally diagnosed cases of D-transposition of the great arteries. We found that an abnormal 3-vessel and trachea view in the shape of an "I" ("I-sign"), which represents an anteriorly displaced aorta, was present in all fetuses with D-transposition of the great arteries when a 3-vessel and trachea view was successfully obtained.

Racial differences in fibroid prevalence and ultrasound findings in asymptomatic young women (18-30 years old): a pilot study.

Objective: 1) To determine the prevalence of fibroids in asymptomatic young black and white women (ages 18-30 y); 2) to determine other differences in uterine and adnexal anatomy; and 3) to obtain preliminary data for sample size calculations.

Design: Pilot cross-sectional study.

Setting: Academic medical center.

Ultrasound evaluation of the endometrium after medical termination of pregnancy.

Objective: To determine ultrasound parameters associated with the need for clinical intervention after mifepristone and misoprostol termination of pregnancy.

Methods: Charts of patients undergoing medical termination according to a standard protocol in a 13-month period were reviewed. Endometrial thickness and the presence of gestational sac, fluid interface, or complex echoes on postprocedure ultrasonogram were recorded.
