To investigate factors that may lead to discordant results in radial and antiradial planes when applying a computer-aided diagnostic system (S-DetectTM) for breast ultrasound (US).



S-DetectTM
Diagnostic performance and diagnostic agreement of the CAD system between the radial and antiradial planes were calculated.  There was no difference in diagnostic performance of the CAD system between the radial and antiradial planes.  The diagnostic agreement of the CAD system between these two orthogonal planes was good (ĸ = 0.645).  The CAD system for breast ultrasound has a favorable diagnostic performance, and discordant CAD results between the radial and antiradial planes were more frequent for BI-RADS category 4A-4B lesions and less invasive malignant lesions.
