| 초록 | Aim: To determine whether lesion size affects the diagnostic performance of apparent diffusion coefficient (ADC) in the evaluation of breast masses. Materials and methods: Consecutive breast lesions detected at magnetic resonance imaging (MRI) from June 2010 to July 2013 were retrospectively reviewed. Differences in the ADCs of benign and malignant mass lesions were compared. Receiver operating characteristics analysis was performed to evaluate diagnostic performance of ADC regarding lesion size (@?1 cm or gt;1 cm) and their T2W signal intensities. Results: Seventy-four malignant lesions (77.9%) and 21 (22.1%) benign lesions were included. Twenty-two of the 95 (23.2%) masses measured @?1 cm (mean 0.73+/-0.4; range 0.51-0.8 cm) and 73/95 (76.9%) masses measured gt;1 cm (mean 2.11+/-0.1; range 1.1-3.3 cm). The mean ADC was significantly lower for malignant than for benign lesions (mean for malignant lesion, 0.89+/-0.29x10 -3 @?mm 2 /s; mean for benign lesions, 1.27+/-0.42x10 -3 @?mm 2 /s; p -3 mm 2 /s with a sensitivity of 85.9% and specificity of 77% for lesions gt;1 cm. The sensitivity and specificity were lowered to 60% and 50%, respectively, for lesions of size @?1. Maximal sensitivity and specificity were reached when the ADC value was used to evaluate T2-dark lesions. Conclusion: Diffusion-weighted MRI is useful for characterizing masses that are hypointense on T2-weighted images. Lower sensitivity and specificity were found for breast lesions @?1 cm |
