A diagnosis of pregnancy location and ultrasound image quality were compared between scans performed with and without the system. Results: Each trainee performed a virtual vaginal examination for all 32 cases with and without use of the system. The analysis of the 128 resulting scans showed higher quality of the images (quality score: +23{\%}; P<.001), less images per scan (4.6 vs 6.3 [without the CDSS]; P<.001), and higher confidence in reporting conclusions (trust score: +20{\%}; P<.001) with use of the system. Further, use of the system cost an additional 8 minutes per scan. We observed a correct diagnosis of pregnancy location in 39 (61{\%}) and 52 (81{\%}) of 64 scans in the nonassisted mode and assisted mode, respectively. Additionally, an exact diagnosis (with precise ectopic location) was made in 30 (47{\%}) and 49 (73{\%}) of the 64 scans without and with use of the system, respectively. These differences in diagnostic performance (+20{\%} for correct location diagnosis and +30{\%} for exact diagnosis) were both statistically significant (P=.002 and P<.001, respectively). Conclusions: The Intelligent Scan Assistant System is based on an expert-validated knowledge base and demonstrates significant improvement in early pregnancy scanning, both in diagnostic performance (pregnancy location and precise diagnosis) and scan quality (selection of images, confidence, and image quality).
