P06.05: Reference ranges of fetal heart biometric parameters by two-dimensional ultrasound: preliminary results

Reference Ranges of Fetal Cerebral Lateral Ventricle Parameters by Ultrasonography.

Objectives This study was done to evaluate the normal fetal cerebral lateral ventricle dimensions with transabdominal ultrasonography. The atrial width (AW), ventricle-to-choroid measurement (V-C), ventricle-to-hemisphere ratio (VHR), and combined anterior horn measurement (CAHM) were taken. Methods This was a cross-sectional study involving 400 normal singleton pregnant subjects whose gestatio...

Longitudinal reference ranges for fetal ultrasound biometry in twin pregnancies

OBJECTIVE The purpose of this study was to establish longitudinal reference ranges for fetal ultrasound biometry measurements and growth parameters in twin pregnancies. METHOD A total of 200 uncomplicated twin pregnancies before 21 weeks of gestation were recruited for this prospective, longitudinal study. Women who abandoned follow-up, pregnancies with unknown outcomes or pregnancies with co...

Fetal Heart Assessment Using Three-dimensional Ultrasound

Cardiac anatomy is complex and often difficult to visualize or comprehend. 3D echocardiography is an area undergoing rapid development that represents a natural extension of conventional sonography methods which require integrating a series of 2D image slices to develop a 3D impression of underlying anatomy or pathology. This paper will review some of the basic concepts behind three-dimensional...

Reference ranges for and determinants of right ventricular area in healthy adults by two-dimensional echocardiography.

BACKGROUND The right ventricular (RV) area is important for diagnosis and follow-up in patients with various diseases, such as in pulmonary hypertension. OBJECTIVES The aim of this study was to define the reference ranges of the end-diastolic RV area in healthy adults and to assess the determining factors. METHODS In the first part of the study 860 healthy subjects (37.6% female; mean age 2...
