To determine the diagnostic value of combining conventional MRI, diffusion-weighted imaging (DWI) and dynamic contrast enhanced MRI (DCE-MRI) in salivary gland tumors.45 patients with tumors were evaluated DWI DCE-MRI prior to surgery confirmed by pathologic findings. The apparent diffusion coefficient (ADC) was calculated from that obtained a factor 0 1000 s mm-2. A time-intensity curve (TIC) DCE-MRI.In benign often showed well-defined clear margins, malignant irregular margins or infiltration into surrounding tissue. There significant differences regard ADC values between pleomorphic adenoma (1.72 ± 0.29 × 10-3 mm2 s-1) (0.95 0.09 s-1, p < 0.05) adenolymphoma (0.74 0.05 (p 0.05). However, there no term (1.33 0.52×10-3 tumors. A-type, B-type D-type TICs, C-type TICs. combination all these parameters yielded sensitivity, specificity, accuracy, positive negative predictive 90%, 97%, 95%, 90 respectively.An evaluation morphologic findings functional (ADCs TIC) appears be useful differentiating Advances knowledge: study firstly dealt DWI-MRI
