False-negative results of breast MR computer-aided evaluation in patients with breast cancer: correlation with clinicopathologic and radiologic factors

PurposeTo investigate clinicopathologic and radiologic factors associated with false-negative results of magnetic resonance computer aided evaluation (MR-CAE) of breast MR imaging (MRI) in breast cancer patients.Materials and MethodsA total of 135 breast cancer patients who underwent preoperative breast MR-CAE were included. False-negative and true-positive MR-CAE results were compared in terms of clinicopathologic and radiologic features. Univariate and multivariate analyses were used to evaluate independent factors associated with false-negative results.ResultSix of 135 cancer patients (4.4%) were false negative on MRI.ConclusionBreast cancer with false-negative results on MR-CAE was classified as a lower BI-RADS category on breast ultrasound than true-positive results on MR-CAE.
