Microbubble contrast imaging of the cardiovascular system of the chick embyro.

Ultrasound imaging of the chick embryo cardiovascular system is limited to B-scan and Doppler technologies. This study demonstrates microbubble contrast imaging of the embryonic cardiovascular anatomy and physiology. Day 8-19 (Hamburger & Hamilton Stage 34-43) chick embryos are examined in ovo using high-frequency ultrasound imaging through an opening in the blunt end (air cell) of the egg.

Computerized grading of anatomy laboratory practical examinations.

At the Medical College of Wisconsin, a procedure was developed to allow computerized grading and grade reporting of laboratory practical examinations in the Clinical Human Anatomy course. At the start of the course, first year medical students were given four Lists of Structures. On these lists, numbered items were arranged alphabetically; the items were anatomical structures that could be tagged on a given lab practical examination.

High frequency ultrasound imaging of the growth and development of the normal chick embryo.

The purpose of this study is to delineate with high frequency ultrasound imaging the normal growth and development of the chick embryo throughout its incubation period. White Leghorn chick embryos were imaged through an opening in the egg air cell from incubation day 0-19 (Hamburger & Hamilton stage 1-45) using a 13 MHz clinical high frequency linear small parts transducer. Multiple anatomic growth parameters were measured.

Preliminary investigation of the use of high frequency ultrasound imaging in the chick embryo.

Background: The purpose of this study was to investigate the feasibility of using high frequency ultrasound to study the chick embryo in a noninvasive and longitudinal fashion.

Methods: A total of 10 SPF White Leghorn chick embryos (GDs 11-17; Hamburger and Hamilton stage 37-43) were consecutively examined with a GE Logiq 400 ProSeries ultrasound unit using an 11-MHz small parts ultrasound probe. Access for ultrasound visualization of the embryos was accomplished by opening a 2-3-cm window either in the air cell over the blunt end of the egg or laterally over the embryo-dependent side of the egg.
