Abstract: Cervical abortion is a spontaneous abortion of a normal intrauterine pregnancy into the cervical canal where the abortus is retained by a closed external 08, causing distention of the cervical canal. This entity closely simulates ectopic cervical pregnancy clinically. The ultrasonic...
Abstract: Growth of the fetal head and abdomen have been monitored by measurement of the head cube (A), the abdominal cube (B) and A/B, from 12 to 41 weeks menstrual age. Growth curves for these parameters have been determined using a specially developed growth curve model (P = c(t)k+S(t)). R2...
Abstract: Static ultrasound was used to examine the cross‐sectional anatomy of the fingers principally to determine the feasibility of demonstrating the normal anatomy of the flexor tendons and also to investigate the possibility of showing pathological anatomy. The study showed that normal and...
Abstract: Quantitative characterization of fetal growth requires the selection of measurement parameters and a growth curve model. For such studies we propose two new parameters (the head cube and the abdominal cube) and a new growth curve model (P = c(t)k+S(t)). These parameters are relatively...
Abstract: In pulsed Doppler echocardiography the maximum measurable velocity is limited due to the aliasing phenomenon. Particularly in cardiac echo studies in adults, aliasing may occur frequently. The principle of and the parameters that influence aliasing will be explained. The importance of...
