Threshold of Apparent Diffusion Coefficient in the Differentiation between Benign and Malignant Breast Lesions on MR Mammography

All MRIs were obtained using a 1.5 Tesla MRI (Optima MR 450W, GE Healthcare, South Carolina, USA) using a bilateral phased-array breast coil. Conventional sequences of routine breast MRI were performed for all patients. The sequences used for the conventional MRI studies were axial STIR and sagittal fat-suppressed T2-weighted (TR/TE, 3850/67.4 ms and 4664/99.8 ms, respectively; slice thickness, 5 mm; matrix, 512 × 512), sagittal T1-weighted (TR/TE, 542/13 ms; slice thickness, 5 mm; matrix, 512 × 512), DWIs and contrast-enhanced three-dimensional dynamic Water VIBRANT-Flex sequences (TR/TE, 7.1/3.3 ms; flip angle, 12°; slice thickness, 1.5 mm; matrix, 512 × 512). One precontrast sequence was followed by six postcontrast sequences for dynamic contrast-enhanced images. Gadopentetate Dimeglumine (Magnevist; Schering, Berlin, Germany) was used as a contrast medium. The contrast medium was given intravenously over 20 s by an automatic MR-compatible injector. The dose was 0.1 mmol/kg.
