Pelvic Ultrasound for Endometriosis: General Features

Three-dimensional ultrasound only differs from 2D ultrasound in the use of a 3D probe and an ultrasound unit with the requisite hardware and software which together create the three-dimensional image. Simply put, 3D ultrasound is a collection of 2D images added together in a ‘volume', a process that creates a unique database that allows reconstruction and evaluation of the scan in different planes, most importantly, and uniquely, a coronal view (Figure 3.3).

3D ultrasound involves the conversion of standard 2D images obtained from ultrasound into a quantitative dataset, which is then reviewed retrospectively [19]. The technique has gained greater attention due to the production of high-quality images with illustrative breast density. Depending on this property, it is leading to adjuncts to mammography [20]. Its use is not prevalent currently, due to the method being relatively new. However, with time, we can expect its usage to increase, compared to its other ultrasound imaging counterparts.
Ultrasound

Three-dimensional (3D) ultrasound examination is not considered a required modality for all pregnant women at this time [4], but it can add accuracy in the assessment of the fetus identified to have anomalies by two-dimensional (2D) ultrasound (especially facial anomalies, neural tube defects, and skeletal malformations). Three-dimensional ultrasound allows the acquisition of volume measurements, which can depict topographic anatomy not able to be seen on 2D imaging. New technology allows for 3D reconstruction of vascular structures, further characterizing vessel relationship [71], vascular malformations, and vascular invasion. It has not been shown to have a clear clinical advantage over traditional ultrasound in routine settings [6].

In women with RIF, thorough investigations must be considered to exclude pelvic pathology. Imaging modalities vary in their characteristics, availability, invasiveness and diagnostic accuracy (Saravelos et al., 2008). Pelvic ultrasonography is an integral part of IVF treatment which helps to diagnose congenital or acquired uterine anomalies. A pooled analysis of 38 studies showed that the highest degrees of overall diagnostic accuracy with the gold standard of hysteroscopy and laparoscopy for detection of uterine cavity abnormalities were, in decreasing order: 3D ultrasound (97.6%), sonohysterography (SHG) (96.5%), hysterosalpingography (HSG) (86.9%) and 2D ultrasound (86.6%). Therefore, 3D ultrasound is a reasonable alternative to hysteroscopy and laparoscopy for diagnosis of uterine anomalies (Grimbizis et al., 2016).
Does Anyone Need to Regulate Parental Access to Fetal Genetic Information?
Published in The American Journal of Bioethics, 2022
Prospective parents have long been interested in knowing as much information about their children as early as possible. This interest is not—and never has been—strictly limited to significant “medical” information. Rather, for a wide variety of reasons, many prospective parents actively seek and welcome whatever information they can obtain about their children in utero. For most of human history, of course, this interest was strictly circumscribed by biological and technological limitations—prospective parents only had “access” to information that could be obtained through internal sensation or external touch or hearing. Over the past century, however, the range of potentially accessible fetal information has expanded significantly. From detecting various health conditions and determining biological sex to providing increasingly realistic 3D and 4D ultrasound images of the fetus, advanced technologies have empowered parents to begin learning about, bonding with, and preparing for their future children well in advance of labor and delivery.
Training the trainees: a pilot study of inter-observer discrepancy and learning curve in the maternal foetal unit of a tertiary centre

Searching of relevant literature revealed no studies directly comparable with ours. Yang et al compare experienced to inexperienced operators, but it is not specified whether the inexperienced group refers to Obstetrics and Gynaecology residents. The same study underlines that the use of 3D ultrasound by a trainee, compared to the traditional 2 D ultrasound, may contribute to a faster biometry scan, as well as to more accurate AC measurements (Yang et al. 2010). However, there are several studies comparing general practitioners to radiology specialists. For example, Lindgaard and Riisgaard (2017) concluded that for low to moderate complexity ultrasound examinations (such as, for abdominal pain/discomfort and possible pregnancy) there was high level of agreement between GPs and gynaecologists.
