- W2375793766 abstract "Objective To evaluate the value of r ADC of diffusion weighted imaging to differential diagnosis of benign and malignant breast lesions. Methods 135 breast lesions,consisting of 44 malignant lesions and 91 benign lesions,underwent conventional MR and DWI( b = 0,800 s / mm2). The ADC of these lesions was measured. The r ADC was equal to the lesion's ADC divided by the ADC of the ipsilateral normal breast tissue. The t-test was used for testing the difference of ADC values between benign and malignant groups,as well as r ADC. Threshold of ADC and r ADC for differential diagnosis was acquired by ROC analysis. Results The ADC values of benign and malignant lesions were( 1. 45 ± 0. 22) × 10-3mm2/ s and( 1. 03 ± 0.19) × 10-3mm2/ s( t =-10. 89,P 0. 05). The corresponding r ADC values were( 0. 72 ± 0. 08) × 10-3mm2/ s and( 0. 49 ±0. 07) × 10-3mm2/ s( t =-15. 35,P 0. 05). The thresholds of ADC,r ADC were 1. 26 × 10-3mm2/ s,0. 62 × 10-3mm2/ s.The sensitivity,specificity and AUC of ADC and r ADC were 82. 4%,95. 5%,0. 944; 84. 6%,90. 9%,0. 961. Conclusion ADC and r ADC values have important values in differentiating benign and malignant breast lesions; especially r ADC values have higher diagnostic sensitivity and accuracy." @default.
