Abstract: The idea of an automated whole breast ultrasound was developed three decades ago. We present our initial experiences with the latest technical advance in this technique, volume scanner (ABVS) ACUSON S2000 TM . Volume data sets were collected from 50 patients and a database containing 23 women no detectable lesions conventional (BI-RADS ® -US 1), 13 clearly benign 2), 14 known cancer 5) created. An independent examiner evaluated ABVS on separate workstation without any prior knowledge patients' histories. diagnostic accuracy for experimental 66.0% (95% confidence interval [CI]: 52.9–79.1). detected all cancers resulting calculated sensitivity 100% described setting CI: 73.2%–100%). After examination, there high number requests second-look ultrasounds 47% 30.9–63.5) healthy (with either lesion or at handheld ultrasound). Therefore, specificity remained 52.8% 35.7–69.2). When comparing concordance gold standard (conventional ultrasound), Cohen's Kappa value as estimation inter-rater reliability κ = 0.37, indicating fair agreement. In conclusion, must still be regarded technique ultrasound, which definitely needs to undergo further evaluation studies. Keywords: cancer, scanner,
