16th World Congress in Fetal Medicine Transvaginal 3D ultrasound and elastography of the cervix as a predictor of cervical incompetency and preterm birth Podobnik-Brlečić P, Podobnik M, Gebauer B, Kurdija K, Jelčić Đ Clinic Podobnik, Zagreb, Croatia Objective To examine the relationship between transvaginal ultrasound cervical changes and pregnancy outcome and ultrasound elastography strain measurements of cervical stiffness in women at risk of cervical incompetency and preterm delivery. Methods In 120 pregnancies with clinical and ultrasound signs of cervical incompetency and preterm delivery, the length of the cervix, the thickness of the anterior wall of the lower uterine segment and the end cervical canal have been evaluated ultrasonically (3D). Strain stiffness was calculated in five regions of interest on anterior cervical lip and correlated to outcome of cervical cerclage and spontaneous preterm delivery. We evaluated these same parameters in 120 healthy pregnancies. An analysis of neonatal outcome was performed using multivariate analysis. Results In patients from 10 to 14 weeks the cervix is significantly longer than in the 25 to 36 weeks group and the anterior wall of the lower uterine segment in the 10 to 14 week group is significantly thicker than in the 20 to 36 week group. In pregnancies at risk for cervical incompetency, cervical lengths and wall thickness were significantly different from those in comparable controls. Strain measurements values, higher than 0.70, were associated with cervical incompetency and strain values, higher than 0.95, were associated with preterm delivery. Forty-five per cent of the patients in the high risk group, with cervical cerclage, delivered at 37.5 weeks and 10.5% of pregnancies ended in abortion when the amniotic membrane herniated into the cervical canal. The frequency of preterm delivery was 55%, 39% and 17% for cervical length of < 10mm, 10-20mm, and 20-30m and stream value of 1.0, 0.92 and 0.80, respectively. Conclusion A shortened cervix with decreased thickness of the anterior wall of lower uterine segment and dilated endocervical canal comparing with ultrasound elastography strain measurements of cervical stiffness show a strong association with cervical incompetency and preterm birth..

Benefits and Risk of Fetal 3D Ultrasound
Benefits and Risk of Fetal 3D Ultrasound ABSTRACT The purpose of this literature review was to survey available information and research related to routine three- dimensional (3D) ultrasound technology in obstetrics, with an emphasis on current medical uses, safety, and availability issues. Several data bases, including Cochrane, WHO, NIH, CINALH, Blackwell Synergy, ERIC, PubMed, and Medline, were used along with information from Internet search engines. Although fetal 3D ultra- sound is used in both medical and commercial settings, recent studies focus on its possible uses rather than the more difficult issues of safety and commercial applications. Professional organizations associated with ul- trasound technology support limiting ultrasounds in pregnancy to medically necessary events, whereas com- mercial venues use “direct to consumer” marketing to promote this technology as a way to “see” the baby be- fore it is born. How safe is routine or frequent use of 3D ultrasound? Further research is needed to address these important questions.

Applications of Advanced Ultrasound Technology in Obstetrics
diagnostics Review Applications of Advanced Ultrasound Technology in Obstetrics Kwok-Yin Leung Obstetrics and Gynaecology, Gleneagles Hong Kong, Hong Kong, China; [email protected] Abstract: Over the years, there have been several improvements in ultrasound technologies including high-resolution ultrasonography, linear transducer, radiant flow, three-/four-dimensional (3D/4D) ultrasound, speckle tracking of the fetal heart, and artificial intelligence. The aims of this review are to evaluate the use of these advanced technologies in obstetrics in the midst of new guidelines on and new techniques of obstetric ultrasonography. In particular, whether these technologies can improve the diagnostic capability, functional analysis, workflow, and ergonomics of obstetric ultrasound examinations will be discussed. Keywords: obstetrics; ultrasound; 3D; 4D; Doppler; artificial intelligence 1. Introduction Ultrasound is widely used in obstetric practice to detect fetal abnormalities with a view to provide prenatal opportunities for further investigations including genetic testing and discussion of management options. In 2010, International Societies of Ultrasound in Obstetrics and Gynecology (ISUOG) published the practice guidelines on the minimal and optional requirements for a routine mid-trimester ultrasound scan [1].

Twenty Bulgarian local goats, aged between 2 and 4 years, weighing 46–52 kg with previously confirmed pregnancy were used in the study. Ultrasound investigations were performed during the 56 - 133 day of pregnancy, at a 2- week interval, via transabdominal approach and an 8.0 MHz linear transducer. Initially, the fetal and uterine structures were visualized in two-dimensional mode (B-mode), and then reconstructed into three-dimensional images using 3D software of the ultrasound machine (SonoScape S2 Vet). The results of this study have shown that 3D ultrasonography is a comparatively easy method to visualize individual parts of the fetus and its internal organs during the second and third pregnancy trimester. At the beginning of the second pregnancy trimester, it was possible visualization and differentiation of 3D ultrasound images of the fetal head and body. At the end of this period (90th day of pregnancy) is visualized clear outline of the skull of the fetus, as well as fetal orbit.

ABSTRACT Breast imaging is an essential cornerstone in the management of breast cancer. It serves not only as breast cancer screening, but also in diagnosis, treatment, and follow-up of patients with breast disease. Attempts to enhance the current imaging modalities and development of new technology are underway. We provide a short overview of the existing imaging modalities including mammography, tomosynthesis, ultrasound and magnetic resonance imaging, and recent technological advances including positron emission mammography, contrast digital mammography, elastography, three-dimensional / contrast-enhanced ultrasound and automated whole- breast ultrasound screening. Magnetic resonance spectroscopy, new state-of-the-art applications in optical imaging, cone-beam computed tomography, magnetic resonance–ultrasound navigation, and molecular imaging techniques are also briefly discussed.
