Introduction: Breast cancer is the most invasive malignant tumour in females worldwide and is the second leading cause of cancer death in females after lung cancer. In Egypt, cancer breast is the first common site of tumours among females (32%) and the second common tumour site in both sexes. The aim of this study was to evaluate and compare the diagnostic performance of quantitative parameters derived from diffusion-weighted imaging (DWI), dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and magnetic resonance spectroscopy (MRS) with ultrasound +/- conventional mammography in differentiating suspicious breast masses (BI-RADS III and IV) and to suggest the most accurate imaging combination for early diagnosis and treatment of cancer breast. Materials and Methods: The study included 40 patients with suspicious breast lesions detected by clinical examination, ultrasound+/- mammography . Dynamic MRI study was performed using 1.5T MRI. Lesions were analyzed regarding their morphology, kinetic curve pattern, ADC value and tCho peak measurement. The results of each MRI parameter were correlated to histo-pathology. Results: In this study sensitivity of sono-mammography was 70% and its specificity was 66.6%. According to using MRI sensitivity was 90% and specificity was 80% by using morphological and curve patterns. As regarding MRS sensitivity was 50% and specificity was 86.7%. Regarding sensitivity of ADC was 90%while its specificity was 93%. The cut off ADC value was 0.95 x 10−3 mm2/s. By using MRI with additive modalities (ADC and MRS) sensitivity was 100% and specificity was 93%. Conclusion: In comparison with MRI, sonomammography alone lack both sensitivity and specificity in detection of breast lesions in suspicious cases. MRI with additive modalities (ADC and MRS) is the best imaging modality in detection of malignant cases and exclusion of benign cases.
