“…The previously published study describes the details of ultrasound performance, quality control of sonographers, generation of the study cohort and data extraction. 10 This is briefly summarised here. The same group of 13 sonographers performed ultrasounds throughout the state, and there is continuous quality control with additional training and supervision as needed.…”

“…1,5 While interpretation of many non-obstetric radiological studies is done remotely, pre-natal ultrasound has traditionally been performed and interpreted in the same location. 10 To our knowledge, there are no large studies validating the accuracy of teleultrasound compared with onsite ultrasound in detecting congenital anomalies. Many interpreting physicians prefer to perform at least part of the study themselves, and the ability to view remote, real-time ultrasound has been limited by technology.…”

“…[5][6][7][8][9] We recently compared the sensitivity and accuracy of 2368 teleultrasounds with the results of published literature for on-site ultrasounds and observed that they were similar. 10 To our knowledge, there are no large studies validating the accuracy of teleultrasound compared with onsite ultrasound in detecting congenital anomalies. We hypothesise that the sensitivity and accuracy of teleultrasound are not inferior to that of on-site ultrasound.…”

Introduction/Purpose: There are no large validation trials comparing teleultrasound to on-site ultrasound. We aim to compare the sensitivity and accuracy of teleultrasound and demonstrate that teleultrasound is not inferior to on-site ultrasound in the pre-natal diagnosis of fetal anomalies. Methods: All targeted ultrasounds performed between November 2010 and December 2012 were considered. We excluded studies performed at less than 17 weeks' gestation, on multiple gestations and for reasons other than an anatomical survey. Postnatal diagnoses were obtained from a state level mandatory birth defects surveillance programme. Descriptive statistics (sensitivity, specificity, positive and negative predictive values and accuracy) were calculated for both groups. A test of noninferiority was performed, with the non-inferiority difference set at 0.15. Results: The teleultrasound and on-site ultrasound groups consisted of 2368 and 3145 studies, respectively. The sensitivity of teleultrasound and on-site ultrasound was 57.46% and 76.57%, and the accuracy was 95.9% and 90.97%, respectively. The observed sensitivity difference was À0.1911. The accuracy, specificity, positive and negative predictive values of teleultrasound are similar to on-site ultrasound. Discussion: Teleultrasound is inferior to on-site ultrasound in the detection of fetal anomalies; however, it has improved accuracy, as well as higher negative and positive predictive values. A negative teleultrasound is more likely to identify a non-anomalous fetus, and a positive teleultrasound is more likely to correctly identify an anomalous fetus. Conclusion: Teleultrasound has an important role in pre-natal diagnosis for those patients unable or unwilling to travel for an onsite ultrasound.

Objectives This study aimed to validate dermatologic ultrasound as a complementary teledermatologic imaging modality in primary and tertiary care centers. Methods Six primary care centers and 1 tertiary care dermatology department collaborated in the program. Images were sent through the institutional teledermatologic platform to the tertiary care dermatology department. At the reference hospital, ultrasound images and clinical data were received and registered by a physician trained in dermatologic ultrasound. An in‐person consultation was scheduled to confirm the teleultrasound diagnosis. The time of response by the tertiary center, quality and size of the teledermatologic image, and concordance with the in‐person diagnosis were assessed for each dermatologic lesion. Results A total of 147 teleultrasound consultations with 143 patients (93 women and 50 men; mean age ± SD, 47 ± 23 years) were evaluated between June 2018 and January 2019. Nine teleultrasound consultations (6.1%) were not valid. Discordance between teleultrasound and the in‐person diagnosis was evident in 6 of 138 cases (4.3%). Most cases corresponded to benign skin tumors (66.7%), followed by inflammatory skin lesions (15.9%), nonmelanoma skin lesions (13%), and other skin lesions (4.3%). All malignant tumors were detected (sensitivity, 100%), although 2 cases of benign lesions were telediagnosed as malignant (specificity, 97.8%). The positive and negative predictive values of a teleultrasound diagnosis of cutaneous malignancy were 90% and 100%, respectively. Conclusions Asynchronous primary care teleultrasound combined with dermatologic ultrasound training at tertiary centers is an effective teledermatologic modality.

Teleultrasound: How Accurate Are We?

Abstract: Teleultrasound for prenatal diagnosis has similar sensitivity and accuracy as the published literature for on-site ultrasound. Further studies are needed to compare the sensitivity and accuracy within the same population and further validate this potentially cost-saving modality.
