| Popis: | Objective: To assess the quality of images and video clips of fetal central nervous (CNS) structures obtained by ultrasound and transmitted via tele-ultrasound from Brazil to Australia. Methods: In this cross-sectional study, 15 normal singleton pregnant women between 20 and 26 weeks were selected. Fetal CNS structures were obtained by images and video clips. The exams were transmitted in real-time using a broadband internet and an inexpensive video streaming device. Four blinded examiners evaluated the quality of the exams using the Likert scale. We calculated the mean, standard deviation, mean difference, and p values were obtained from paired t tests. Results: The quality of the original video clips was slightly better than that observed by the transmitted video clips; mean difference considering all observers ¼ 0.23 points. In 47/60 comparisons (78.3%; 95% CI ¼ 66.4–86.9%) the quality of the video clips were judged to be the same. In 182/240 still images (75.8%; 95% CI ¼ 70.0–80.8%) the scores of transmitted image were considered the same as the original. Conclusion: We demonstrated that long distance tele-ultrasound transmission of fetal CNS structures using an inexpensive video streaming device provided images of subjective good quality. |
