A Body Navigation-Loaded Ultrasound Acquisition Technology: A Pilot Comparison with Conventional Ultrasound

Background: In conventional ultrasonography, the ultrasound image is not labeled with information on location or orientation of transducer. There also no parts body under examination. Objectives: This study aimed to investigate efficacy navigation-loaded including real-time transducer and inspection site, compared ultrasound. Patients Methods: After obtaining approval from institutional review board, 29 healthy adult volunteers were prospectively enrolled in this study. One gastrointestinal radiologist performed an abdominal ultrasound, using navigation convergence system, developed by authors. Subsequently, equivalent set was prepared. Three radiologists independently evaluated two sets for identifying target organ (two points), (one point). a two-week interval, images first analyzed, then, examined. The score differences between second evaluations Wilcoxon signed-rank test. inter-rater agreement three reviewers determined measuring Fleiss’ kappa value. Results: A total 1,402 acquired operator carefully selected 203 analysis. interpretation all significantly increased each examination analysis (reviewer A, 4.07 ± 1.56 4.79 0.69; reviewer B, 3.83 1.59 4.49 0.88; C, 3.43 1.60 4.19 1.01) (P < 0.0001). Conclusion: According results pilot study, technology can assist simple objective organs.
