摘要:

AbstractWe have identified six cases of chorioamniotic separation, three diagnosed in the third trimester and three cases seen in early pregnancy, at or prior to 16 wk' gestation. The sonographic findings consist of a fine mobile echodense line separated from the chorion and uterine wall by a lucent space. The membrane may completely surround the fetus and may extend over the fetal surface of the placenta, in which case the chorion may be identified as a separate echo. Two patients with chorioamniotic separation in the third trimester had polyhydramnios. The infants had no manifestations of amniotic band syndrome. The membranes seen in four other conditions are described and compared with chorioamniotic separation.

摘要:

AbstractThis review discusses the problem of detecting intrauterine growth retardation (IUGR) with ultrasound. A new procedure for standardizing the reporting of such studies is presented. Using this standard format, the results obtained by various investigators using a variety of parameters are summarized, compared and evaluated. Suggestions for standardizing such investigations are presented.

摘要:

AbstractCalculation of total intrauterine volume (TIUV) has become an important part of obstetric sonography in the evaluation of possible intrauterine growth retardation. However, a number of problems with the measurements and the calculation itself limit the reliability of this determination. More reliable measurements may be obtained through rigid standardization of technique. However, a certain amount of inaccuracy is inherent in the procedure and cannot be corrected.

摘要:

AbstractBlood flow in the umbilical cord and placenta has been observed with real‐time sonography. In some of the larger “cystic” spaces within the placenta a pattern of pulsatile, whorling, and accelerating flow is seen, suggesting an arteriovenous conne

摘要:

AbstractTwo moving string test targets have been developed and used to characterize ultrasound Doppler instrumentation. The characteristics investigated were sample volume size and location. The tests were performed on a combined echo/Doppler instrument and on an annular array system. The procedures can be carried out routinely in the clinical laboratory to ensure that the instrument is working properly or as an aid for correct interpretation of acquired data.

摘要:

AbstractA study that investigated the applicability of M‐mode echocardiography in a group of obese adults who were referred to the clinical echocardiographic laboratory is summarized. The M‐mode echocardiographic imaging technique, as performed with currently available equipment, permitted visualization of the cardiac anatomy in a majority of the patients. Comparable clinical information may be difficult to obtain by other meth
