Observer Agreement Using the ACR Breast Imaging Reporting and Data System (BI- RADS)-Ultrasound, First Edition (2003)Observer Agreement • October 5th, 2007
Materials and Methods: Two hundred ninety three female patients with 314 lesions underwent US-guided biopsies at one facility during a two-year period. Static sonographic images of each breast lesion were acquired and reviewed by four radiologists with expertise in breast imaging. Each radiologist independently evaluated all cases and described the mass according to BI-RADS-US. To assess intraobserver variability, one of the four radiologists reassessed all of the cases one month after the initial evaluation. Inter- and intraobserver variabilities were determined using Cohen’s kappa (k) statistics.
