RESUMO
PURPOSE: To compare the diagnostic accuracy of radiologists interpreting static ultrasonographic (US) images electronically transmitted to an academic medical center (remote radiologists) with that of radiologists performing "hands-on" US at a community-based outpatient site (on-site radiologists). MATERIALS AND METHODS: During 8 months, 80 patients underwent pelvic US at a community-based outpatient site. Images were electronically transmitted to a remote medical center as they were acquired at the community site and were printed on a laser printer identical to the one used at the outpatient site. The reference standard for correct diagnosis was based on histopathologic findings (n = 13), additional imaging results (n = 34), or review by a second independent observer (n = 33). Both an on-site and a remote radiologist interpreted the images, and their interpretations were rated as agree, both correct; agree, both incorrect; or disagree. Cases of disagreement were rated as major or minor. RESULTS: On-site and remote radiologists agreed in 69 of 80 patients (86%), and both radiologists were correct in all of these cases. There were 10 minor discrepancies and one major discrepancy. The diagnostic accuracies of the one-site and remote radiologists were 92% and 94%, respectively. CONCLUSION: High levels of diagnostic accuracy can be achieved by radiologists interpreting static US images. Strict protocols and excellent communication between the radiologist and sonographer are necessary to avoid diagnostic errors.
