Ultrasonic assessment is a new approach to assess both quality and density. Two ultrasonic parameters are measured on the os calcis: the attenuation or broadband ultrasound attenuation (BUA) and the velocity or speed of sound (SOS). The interunit variations in vitro and in vivo of an ultrasound inst

✦ Synopsis
Real-time ultrasound was used in 654 consecutive pregnancies to obtain standard growth parameters for the fetal brain. Measurement of the width of the lateral ventricle (LVW) and hemisphere and their relationships to menstrual age, biparietal diameter, and birth weight were determined. The growth of the LVW was to a great extent independent of birth weight but dependent on menstrual age. Thirteen fetuses with a single ventricular width measurements exceeding +2 SD from the mean were separately evaluated, and all but one case were found to be normal.

The main anatomical features of the subependymal veins of the lateral ventricles are summarized. The important role of the subependymal veins for the study of the size and shape of the lateral ventricles is outlined. The most typical modifications which occur in cases of ventricular enlargement or v
This investigation is concerned with establishing the anatomical location of the site proposed for making fetal thigh circumference (ThC) measurements with ultrasound. An evaluation of the accuracy of ultrasonic ThC measurements has also been made. The results of these studies indicate that the chan
## Abstract In this prospective study we have used ultrasonographic measurements of the cross-sectional area of transplanted kidneys, as an objective assessment of graft size, for diagnosis of acute rejection episodes. Sixty episodes of acute graft dysfunction (serum creatinine rise of ≥ 30 μmol/l)
