Telesonography: Virtual 3D image processing of remotely acquired abdominal, vascular, and fetal sonograms

Objective: The aim of the present study was to determine the correlation between fetal liver length (FLL) at the 11+0-13+6 week of pregnancy and crown-rump length (CRL).Methods: Pregnant women (n=63) referring to the Başkent University Konya Hospital Obstetrics and Gynecology Clinic between January and March 2014 for first trimester screening were included in the study. Patients were excluded for the following reasons: two for type II DM, one for metabolic disease, and three because they refused to share their information. FLL was measured in patients at the 11+0-13+6 week of gestation and in those who had normal ultrasonographic findings. Exclusion criteria were as follows: nuchal translucency of ≥3.5 mm, antenatal first trimester combined test results of ≥1/250, reverse flow of the ductus venosus and tricuspid valve, absence of nasal bone (NB), and fetal malformation in second trimester. Fiftyseven women who fulfilled inclusion criteria were included in the study. Statistical Package for the Social Sciences version 15.0 (SPSS, Inc., Chicago, IL, USA) was used for statistical analysis. Descriptive statistics and Pearson's correlation test was used for correlation between FLL and CRL.Results: Mean age of patients was 28. 18±4.7 (19-39). Mean gravida and parity were 2.05±1.2 (1-6) and 1±0.8 (0-5), respectively. Mean gestational age was 12.4 weeks (min: 11.1 -max: 13.6), and mean FLL of the study group was 11.2±1.1 mm (8.2-13.7 mm). Mean NT was 1.1±0.3 (0.5-2.4) mm. In the present study, it was established that FLL was correlated with CRL (r (57): 0.840; p<0.001).Conclusion: This study showed that there was a significant, strong, positive correlation between FLL and CRL at the 11 th -13 th week of pregnancy.

“…This 3D reconstruction program, of which the diagnostic accuracy for general abdomen ultrasound was estimated at 91% in a previous study (6), enables the expert to review the images sent by the untrained person at a later time and make a radiological diagnosis. Ultrasonography involves a degree of technical skill and precision, and thus it is quite operator dependent.…”

“…In the absence of a sonographer at the patient center, an expert is able to make a radiological diagnosis in delayed time from ultrasound video sequences sent by an untrained user, with the use of the 3D virtual navigation program ECHO-CNES (Unité de Médecine et Physiologie Spatiales de Tours) (6). For tele-ultrasound, the computer at the patient center (isolated site) is beforehand connected to the ultrasound device via a video converter/USB (Pinnacle for example).…”

Purpose: To design a “low-cost” tele-imaging method allowing real-time tele-ultrasound expertise, delayed tele-ultrasound diagnosis, and tele-radiology between remote peripherals hospitals and clinics (patient centers) and university hospital centers (expert center).Materials and methods: A system of communication via internet (IP camera and remote access software) enabling transfer of ultrasound videos and images between two centers allows a real-time tele-radiology expertise in the presence of a junior sonographer or radiologist at the patient center. In the absence of a sonographer or radiologist at the patient center, a 3D reconstruction program allows a delayed tele-ultrasound diagnosis with images acquired by a lay operator (e.g., midwife, nurse, technician). The system was tested both with high and low bandwidth. The system can further accommodate non-ultrasound tele-radiology (conventional radiography, mammography, and computer tomography for example). The system was tested on 50 patients between CHR Tsevie in Togo (40 km from Lomé-Togo and 4500 km from Tours-France) and CHU Campus at Lomé and CHU Trousseau in Tours.Results: A real-time tele-expertise was successfully performed with a delay of approximately 1.5 s with an internet bandwidth of around 1 Mbps (IP Camera) and 512 kbps (remote access software). A delayed tele-ultrasound diagnosis was also performed with satisfactory results. The transmission of radiological images from the patient center to the expert center was of adequate quality. Delayed tele-ultrasound and tele-radiology was possible even in the presence of a low-bandwidth internet connection.Conclusion: This tele-imaging method, requiring nothing by readily available and inexpensive technology and equipment, offers a major opportunity for telemedicine in developing countries.

“…Specifically, we observed the presence of imaging informatics publications released in 2014 (N=4). These publications described the improvement of imaging services by integrating systems, reducing cost, using mobile devices, applying new imaging techniques in LMICs, and exploring new methods to identify and compare data in images [120][121][122][123][124]. Reviewers also identified an additional theme related to emergency services supported by information systems in LMICs [125][126][127].…”

Objective: To categorize and describe the public health informatics (PHI) and global health informatics (GHI) literature between 2012 and 2014.Methods: We conducted a semi-systematic review of articles published between January 2012 and September 2014 where information and communications technologies (ICT) was a primary subject of the study or a main component of the study methodology. Additional inclusion and exclusion criteria were used to filter PHI and GHI articles from the larger biomedical informatics domain. Articles were identified using MEDLINE as well as personal bibliographies from members of the American Medical Informatics Association PHI and GHI working groups.Results: A total of 85 PHI articles and 282 GHI articles were identified. While systems in PHI continue to support surveillance activities, we identified a shift towards support for prevention, environmental health, and public health care services. Furthermore, articles from the U.S. reveal a shift towards PHI applications at state and local levels. GHI articles focused on telemedicine, mHealth and eHealth applications. The development of adequate infrastructure to support ICT remains a challenge, although we identified a small but growing set of articles that measure the impact of ICT on clinical outcomes.Discussion: There is evidence of growth with respect to both implementation of information systems within the public health enterprise as well as a widening of scope within each informatics discipline. Yet the articles also illuminate the need for more primary research studies on what works and what does not as both searches yielded small numbers of primary, empirical articles.Conclusion: While the body of knowledge around PHI and GHI continues to mature, additional studies of higher quality are needed to generate the robust evidence base needed to support continued investment in ICT by governmental health agencies.
